        Tagging repository contents with Blitz_0_9 tag.
	* m4/ac_compiler_specific_header.m4: Added support for PathScale
	pathCC compiler.
	* doc/download.texi: Added reference to the newer blitz project
	page on SourceForge.
	* doc/help.texi: Updated the Help page to refer to the newer
	SourceForge project page and mailing lists for blitz.
	* doc/install.texi: Minor updates to the notes on configuration
	and installation of blitz.
	* doc/platforms.texi: Updates to platform and compiler notes.  I
	tried to add a comment for every platform/compiler combination
	that has active or historical support.

2005-10-13  Julian Cummings  <[e-mail]>

	* doc/faq.texi: Added a few items that have been asked about a lot
	over the past year, including configuration under Mac OS X, the
	Fortran compiler requirement, and the need to include the
	<blitz/tinyvec-et.h> header.
	* doc/arrays-globals.texi: Added information on the newer global
	Array functions swap() and find().
	* blitz/array-impl.h: Slight simplification of swap() function.
	* configure.ac: Changed blitz version number from 0.8.1 to 0.9 as
	we agreed upon.  We will reserve use of the patch number only when
	providing a single critical patch.
	* examples/random.cpp: Added a few lines of code to briefly
	exercise the new get/set state interface.
	* random/mt.h: Added implementation of get/set state for the
	MersenneTwister IRNG, as suggested by Patrik Jonsson
	([e-mail]), with minor corrections and modifications.
	* random/default.h: Added interface for getting or setting the
	state of the IRNG, as suggested by Patrik Jonsson
	([e-mail]).

2005-10-13  Patrick Guio <[e-mail]>

	* doc/Makefile.am: Changed options to texi2html for compatibility
	to both v1.64 and v.176.


2005-10-11  Julian Cummings  <[e-mail]>

	* examples/.cvsignore: Added matlab output files to cvs ignore
	list.
	* doc/doxygen/.cvsignore: Added doxygen-warning message file to
	ignore list.
	* .cvsignore: Added older ChangeLog_ files to ignore list.
	* blitz/.cvsignore: Oops!  I put the ChangeLog_ stuff in the wrong
	cvsignore file.
	* blitz/.cvsignore: Added old ChangeLog_ files and pathscale
	compiler directory.
	* blitz/memblock.h: Removed the restrict qualifier from a few
	places where it was being used inappropriately with pointers as
	function parameters.  These were flagged by the IBM xlC compiler.
	Basically, you cannot assign a restricted pointer to another
	pointer that is in an outer (containing) scope because you may be
	creating an alias outside of the current scope.

2005-10-11  Patrick Guio <[e-mail]>

	* doc/Makefile.am: Added option to specify the . location for 
	HTML files generated by texi2html since the newer texi2html v1.76
	provided by Fedore Core 4 creates a subdirectory to put these 
	files by default.
	* doc/random.texi: Fixed @math expression that caused trouble
	to newer texi2html v1.76 into conditional expression statements 
	@iftex/@ifinfo/@ifhtml.
	* doc/blitz.texi: Moved texinfo's @setcontentsaftertitlepage
	command into @iftex block since it caused trouble to newer
	texi2html v1.76.


2005-10-10  Julian Cummings  <[e-mail]>

	* benchmarks/loopstruct.cpp: Added hack for Compaq cxx compiler,
	which does not provide support for writing out the long double
	type in std ansi mode.
	* blitz/timer.h: Added hack for Compaq cxx compiler, which does
	not provide support for writing out the long double type in std
	ansi mode.
	* doc/doxygen/Makefile.am: Added an uninstall-hook target to clean
	up doxygen install dir.
	* configure.ac: Added Pathscale compilers to default compiler
	search lists.  Bumped blitz package version number to 0.8.1.  A
	few more minor fixes and doc updates before we actually release
	the new version, but we're close now!
	* blitz/bzconfig.h: Added section for Pathscale compiler-specific
	header.
	* m4/ac_fortran_flags_preset.m4: Added support for Pathscale
	pathf90 compiler.
	* m4/ac_cxx_flags_preset.m4: Added support for Pathscale C++
	compiler (pathCC).
	* blitz/Makefile.am: Added list of compiler-specific header files
	to list of files to be removed by distclean.  One
	compiler-specific header file will always be present within the
	distribution.
	* Makefile.am: Added pkgconfig data files to list of files to be
	removed by distclean.

	* blitz/array/newet-macros.h: Greatly simplified the definitions
	of the BZ_DECLARE_FUNCTION macros by utilizing the previously
	defined macros BZ_DEFINE_UNARY_FUNC, BZ_DEFINE_BINARY_FUNC, etc.
	This follows a suggestion from Peter Kummel
	([e-mail]).
	* blitz/funcs.h: Added macros BZ_DEFINE_TERNARY_FUNC and
	BZ_DEFINE_TERNARY_FUNC_RET for completeness, although there are no
	standard library math functions that require such macros.
	Reordered to list complex unary funcs after all ordinary unary
	funcs and complex binary funcs after all ordinary binary funcs.
	Renamed macro BZ_DEFINE_BINARY_CFUNC2 to
	BZ_DEFINE_BINARY_FUNC_CRET in order to (hopefully) clarify that
	this is for a binary func that takes ordinary floating-point args
	and returns a complex type.
	* blitz/array-impl.h: Added a find() function along the lines of
	what was suggested by Jonathan Stickel ([e-mail])
	as an analogue to the Matlab find().  This function takes a 1d
	Array of TinyVector indices and an Array or _bz_ArrayExpr, and it
	stores all the index positions where the Array or expression is
	true.  Also, I removed the annoying external include guards here
	(need to do this universally throughout blitz at some point).
	* testsuite/tinyvec.cpp: Added minimal testing of begin()/end()
	method and TinyVector iterators.
	* m4/ac_cxx_flags_preset.m4: Remove flag that was disabling use of
	new type promotion system with icpc compiler.  This problem should
	now be fixed.
	* blitz/promote.h: Substituted for defaultPromotion in expression
	for promoteToT1 in order to eliminate an error from the Intel
	compiler on this file.  The icpc compiler thought the expression
	was not a compile-time constant value.  This will allow us to once
	again use the newer type promotion system with icpc.

	* blitz/bzconfig.h: Modify include paths to have the blitz/
	prefix.  Use angled brackets instead of quotes around header file
	name.  Added error message if compiler unknown.
	* lib/Makefile.am: Simplified include file search path flags.
	* blitz/array/domain.h: Introduces an empty constructor and a
	constructor from a vector of Ranges.  New typedef used to simplify
	the code. Constification of many methods.  Added non-const ubound
	and lbound methods for RectDomain.  Removed external include
	guards.
	* blitz/array-impl.h: Allow components to be referred with
	unsigned.

2005-10-06  Julian Cummings  <[e-mail]>

	* blitz/generate/genpromote.cpp: Eliminate gcc-4.0.0 compiler
	warning about using an anonymous struct (thanks Theo!).
	* blitz/generate/Makefile.am: Repaired clean-local target.  Added
	header file dependencies.
	* blitz/generate/operands.h: Changed initialization method for
	vector types from begin() to beginFast() to avoid conflict with
	standard begin() method that is expected to produce an STL
	iterator.
	* blitz/vecexpr.h: Change begin() to beginFast().
	* blitz/vecpick.cc: Change begin() to beginFast().
	* blitz/vecpick.h: Change begin() to beginFast().
	* blitz/vector.cc: Replaced begin() with beginFast().
	* blitz/vector.h: Changed begin() to beginFast().  Need to add an
	STL-compliant iterator for Vector.
	* blitz/tinyvec.cc: Replace begin() with beginFast().
	* blitz/tinyvec.h: Renamed pre-existing begin() method beginFast()
	to avoid conflict with standard begin() method that is presumed to
	deliver an STL-compliant iterator.  TinyVectorIter and
	TinyVectorIterConst are not STL compliant at all and are really
	just glorified indices.  Define begin() and end() to return raw
	data pointers instead, since these will have the STL iterator
	semantics automatically.

2005-10-03  Julian Cummings  <[e-mail]>

	* README-VS.NET.txt: Updated README file for VS.NET stuff to
	mention new Blitz-Examples solution file.
2005-09-29  Theodore Papadopoulo <[e-mail]>

    * blitz/tinyvec.h: Constified many methods. Added a end() method.
    Returning const references insteadof copies for operator() const
    and operator[] const.

    * blitz/tinyvec.cc: Constified many methods accordingly.
    
2005-08-23  Julian Cummings  <[e-mail]>

	* testsuite/complex-test.cpp: Added some tests of math ops with
	complex<long double> type.

	* blitz/array/ops.h: Added missing support for math operations
	between complex<long double> Array and scalar types.

2005-07-27  Julian Cummings  <[e-mail]>

	* blitz/memblock.h: Fixed problem with the deleteDataWhenDone
	policy.  It was not actually deleting the data as expected.
	Solution was to set dataBlockAddress_ pointer to the address of
	the preexisting memory in MemoryBlock constructor.  In subclass
	UnownedMemoryBlock constructor, we reset this pointer to 0 to
	indicate that any preexisting memory is not our responsibility.
	* Makefile.am: Use new FORTRAN_ENABLED conditional to only build
	in the benchmarks directory if Fortran compilation is enabled.
	* configure.ac: Added conditional to indicate whether Fortran
	compilation (needed for the benchmark codes) has been enabled.
	* blitz/array/map.h: Added return of dummy T_numtype object in
	generic version of map method to eliminate possible compiler
	warning about no return statement in non-void function.

2005-07-07  Julian Cummings  <[e-mail]>

	* blitz/memblock.h: Removed the swap() method that was added here.
	The Array method reference() uses the existing
	MemoryBlockReference method changeBlock() to implement a swap of
	the memory block in a safer manner with reference counting.
	* blitz/array-impl.h: Modified Theo's implementation of the swap()
	function to use the existing reference() method.  This is easier
	and does not require the swap() function to be a friend of the
	Array class.  The MS VS.NET C++ compiler was confused by the
	tricky syntax for templated functions that are friended and using
	the friend feature of C++ is a bad idea anyway.  There may be a
	tiny bit more overhead with this implementation because it
	constructs a null temporary Array, but the temporary allocates no
	space for data elements, only for Array metadata and the Array
	ordering description.

2005-06-16  Julian Cummings  <[e-mail]>

	* m4/ac_cxx_template_qualified_base_class.m4: Fixed up the
	compiler test for support of template-qualified base classes to
	work properly under the new gcc 4.0.0 compiler by adding the full
	template specialization syntax and explicitly qualifying the call
	to f in the base class as required by the ANSI standard.

2005-06-16  Theodore Papadopoulo <[e-mail]>

    * blitz/memblock.h: Added support for swapping memblocks.
    * blitz/array-impl.h: Added support for swapping arrays using the
    memblock swapping.

2005-06-02  Julian Cummings  <[e-mail]>

	* blitz/vecmax.cc: Put parentheses around "max" in definitions of
	max() function for Vector-like objects, to avoid triggering any
	max macro that may be defined.  A workaround for sloppiness in
	boost and Windows header files.

	* blitz/vecmin.cc: Put parentheses around "min" in definitions of
	min() function for Vector-like objects, to avoid triggering any
	min macro that may be defined.  A workaround for sloppiness in
	boost and Windows header files.

2005-05-24  Julian Cummings  <[e-mail]>

	* blitz/array/ops.h: Use new BZ_DECLARE_ARRAY_ET_BINARY_TINYVEC
	macro to declare the standard binary math operations between an
	Array-like object and a TinyVector.  The TinyVector is treated
	like a scalar in these operations, interacting with each element
	of the Array separately.
	* blitz/array/newet-macros.h: Added macro
	BZ_DECLARE_ARRAY_ET_BINARY_TINYVEC to generate code for binary
	math operations between any Array-like type and a TinyVector.  The
	TinyVector is treated as a scalar-like type and the operation is
	performed between the TinyVector and each element of the
	Array-like object.  The definitions for binary operations between
	the TinyVector and the Array element type should be provided
	elsewhere in <blitz/vector-et.h>.

	* blitz/array/iter.h: Modified postfix operator++ for
	ConstArrayIterator and ArrayIterator to return the iterator object
	by value rather than by const reference, since you are returning a
