	m4/ac_lib_blas.m4 m4/ac_prog_doxygen.m4 m4/ac_send_config.m4: New files. 
	M4 macros containing functions definitions for the configure.in autoconf file. 
	* acinclude.m4: Removed. Renamed m4/blitz.m4.
	* m4/blitz.m4: New file. Old acinclude.m4.
	* Makefile.am configure.in: Updated to use the new m4 macros in m4 directory.
	configure.in now integrates all the C++ feature tests handled earlier by
	compiler/bzconfig. 
	It creates the file blitz/new-config.h from the template file
	blitz/new-config.h.in. blitz/new-config.h replaces blitz/config.h earlier
	generated by compiler/bzconfig. 
	The --with-cxx option is removed and replaced by standard variable parsing. 
	The C++ compiler flags preset can be overwritten with the new option
	--disable-cxx-flags-preset. 
	Fortran 77/90 compilers and flags can be overwritten with the new option
	--disable-fortran-flags-preset.
	For more help check configure --help.
	* blitz/compiler.h: Include blitz/new-config.h instead of blitz/config.h.
	* blitz/Makefile.am: Added new-config.h as a file to install.
	* blitz/benchext.cc blitz/benchext.h: Added optional argument for
	saveMatlabGraph to be able to plot 2d graph with requested Matlab command (other 
	type than the earlier default semilogx).
	* benchmarks/Makefile.am: Cleaned the Fortran 77/90 variables definitions.
	Make use of the new FC* variables system introduced in configure.in.
	* benchmarks/loop25.cpp: Corrected number of arithmetic operations to be 6.

	* config/texinfo.tex config/mdate-sh: New file. Replace doc/texinfo.tex 
	doc/mdate-sh.
	* doc/texinfo.tex doc/mdate-sh: Removed. Replaced by config/texinfo.tex
	config/mdate-sh.
	* m4/ac_cxx_flags_preset.m4 m4/ac_fortran_flags_preset.m4: Fixed
	unsupported syntax variable assignement of several strings on several
	lines to one long string.
	* benchmarks/Makefile.am: Fixed clean-local target core* into core.[0-9]*.
	* m4/ac_cxx_flags_preset.m4: Fixed CXXFLAGS flag for Compaq cxx ver.>=6.3.

	* doc/examples/Makefile.am: Added $(EXEEXT) to program names when
	listed as prerequisites for .out files, so these executables get
	built properly on platforms where executables do have a filename
	extension.

2004-02-09  Julian Cummings  <[e-mail]>

	* blitz/array/newet-macros.h: Added new macro
	BZ_DECLARE_FUNCTION2_SCALAR, which allows the user to declare that
	a user-defined binary function may be applied to a combination of
	an Array type and the given scalar type.  This macro is intended
	to be used in conjunction with either BZ_DECLARE_FUNCTION2 or
	BZ_DECLARE_FUNCTION2_RET, which declare a user-defined binary
	function applicable to a pair of Array types.  The arguments for
	BZ_DECLARE_FUNCTION2_SCALAR are the function name and the scalar
	argument type.

2004-02-05  Julian Cummings  <[e-mail]>

	* blitz/array/newet-macros.h: Added space between macro argument
	"sca" and closing angled bracket ">" to accommodate the use of a
	scalar type that is a template, such as complex<double>.  This
	eliminates errors reported by the Intel icc compiler.

2004-01-20  Julian Cummings  <[e-mail]>

	* blitz/array/ops.cc: Removed inline keyword from
	Array::initialize() member function, since this triggers a bug in
	the gcc optimizer when repeatedly assigning a scalar to an Array
	slice.
	* blitz/memblock.cc: Changed argument type for member function
	allocate() from int to size_t and made type usage consistent
	throughout this function.

	* blitz/memblock.h: Changed argument type for member function
	allocate() from int to size_t to eliminate unintended type
	conversion.  Also fixed internal include guard, removed external
	include guards and added Emacs C++ tag.

	* blitz/vector.h: Consolidated multiple versions of copy
	constructor with const and non-const reference argument into a
	single version to eliminate compiler warning.  Also eliminated
	external include guards and added Emacs C++ tag.

2004-01-08  Julian Cummings  <[e-mail]>

	* examples/prettyprint.cpp: Replaced use of obsolete macro kludge
	_bz_true with ANSI C++ boolean value true.

2004-01-06  Julian Cummings  <[e-mail]>

	* blitz/array/iter.h: Fixed bug in ConstPointerStack assignment
	operator.

2003-12-30  Julian Cummings  <[e-mail]>

	* testsuite/extract.cpp: Use new BZ_DECLARE_ARRAY_ET_SCALAR_OPS
	macro to provide binary operators that combine an Array and an
	RGB24 object.  This is needed here to provide the definition for
	operator==.  This is an example of how to place a user-defined
	concrete data type into the blitz ET system.

	* testsuite/newet.cpp: Removed the final test in this testsuite
	code, which was attempting to invoke a ternary functor with one of
	the arguments being a scalar int.  This no longer works because
	the ternary operator definition has been modified to accept only
	Array-like ETBase<T> objects.  This seems like a more reasonable
	behavior.  One could define ternary combinations that involve one
	or two scalar objects and convert them into _bz_ArrayExprConstant
	objects, but I'm not sure there is any real need for such
	operators.

	* blitz/array/funcs.h: Added new macro
	BZ_DECLARE_ARRAY_ET_SCALAR_FUNCS that provides binary functions
	for combinations of an ETBase<T> and a scalar type.  This macro is
	used to provide binary funcs for Array-like objects interacting
	with all the common built-in scalar types.  It can also be used to
	define similar functions with a user-defined scalar type.

	* blitz/array/ops.h: Added new macro
	BZ_DECLARE_ARRAY_ET_SCALAR_OPS that provides binary operators for
	combinations of an ETBase<T> and a scalar type.  This macro is
	used to provide binary ops for Array-like objects interacting with
	all the common built-in scalar types.  It can also be used to
	define similar operators with a user-defined scalar type.

	* blitz/array/zip.h: Renamed class _bz_ArrayExprOp to
	_bz_ArrayExprBinaryOp for imporoved clarity.

	* blitz/array/newet-macros.h: Renamed class _bz_ArrayExprOp to
	_bz_ArrayExprBinaryOp for imporoved clarity.  Reduced the
	complexity of the BZ_DECLARE_ARRAY_ET_BINARY macro.  This macro
	now applies only to the combination of an ETBase<T1> and an
	ETBase<T2>, so the operands must be Arrays or Array
	expression-like objects.  Interactions between an ETBase<T> and a
	scalar type are handled by a new macro called
	BZ_DECLARE_ARRAY_ET_BINARY_SCALAR, which converts the scalar into
	an expression object using the asExpr class.  The advantage of
	this approach is that we have fewer combinations to handle and we
	can avoid ambiguities that might arise with general function
	templates.

	* blitz/array/asexpr.h: Renamed class _bz_ArrayExprOp to
	_bz_ArrayExprBinaryOp for imporoved clarity.  Added static method
	getExpr() to asExpr class to convert the given type into the
	T_expr type needed for expression evaluation.  This allows us to
	reduce the number of specializations of binary operators by
	treating all ETBase<T> objects in a uniform fashion.

	* blitz/array/expr.h: Renamed class _bz_ArrayExprOp to
	_bz_ArrayExprBinaryOp for imporoved clarity.  Some other cosmetic
	changes as well.

	* blitz/array/bops.cc: Regenerated blitz/array/bops.cc header
	file.

	* blitz/array/uops.cc: Regenerated blitz/array/uops.cc header
	file.

	* blitz/generate/genarruops.cpp: Renamed _bz_ArrayExprOp class to
	_bz_ArrayExprBinaryOp for improved clarity.

	* blitz/generate/genarrbops.cpp: Renamed _bz_ArrayExprOp class to
	_bz_ArrayExprBinaryOp for improved clarity.

	* blitz/array/where.h: Removed some previously commented out code.
	Added Emacs C++ tag.
	* blitz/array/ops.cc: Replaced static_cast of ETBase objects with
	call to unwrap() member function.  Also removed external include
	guards.

	* blitz/array/newet-macros.h: Replaced static_cast of ETBase
	objects with call to unwrap() member function.  Also added Emacs
	C++ tag at top of file.

	* blitz/array/functorExpr.h: Replaced static_cast of ETBase
	objects with call to unwrap() member function.  Also added Emacs
	C++ tag and Blitz file header at top of file.

	* blitz/array/funcs.h: Replaced static_cast of ETBase objects with
	call to unwrap() member function.  Also added Emacs C++ tag at top
	of file and removed external include guards.

	* blitz/etbase.h: Added unwrap() member function to ETBase class
	that performs the static cast to produce the wrapped type.  Also
	added Emacs C++ tag at top of file.
