	* include/pkgconf/libm.h:
	* src/misc/compatmode.cxx, src/misc/signgam.cxx:
	* tests/vectors/vector_support.h

	Updated for new kernel configuration option symbol names

	* tests/vectors/vector_support.h: 
	Change START_TEST macro, adjust config options and add
	cyg_package_start() to get tests working correctly with new entry
	point mechanism, including cyg_iso_c_start() if available

Wed Aug 26 20:25:36 1998  Jonathan Larmour  <[e-mail]>

	* include/pkgconf/libm.h: 
	Remove #define CYGPKG_LIBM is that is meant to live in
	<pkgconf/system.h> after all


Wed Aug 26 19:38:54 1998  Jonathan Larmour  <[e-mail]>

	* include/pkgconf/libm.h:

	Untabify

Mon Jul 27 22:52:24 1998  Jonathan Larmour  <[e-mail]>

	* tests/vectors/vector_support.h (doTestVec):

Mon Jul 27 22:45:01 1998  Jonathan Larmour  <[e-mail]>

	* tests/vectors/vector_support.h (checkErrorAcceptable): 
	Add extra check for tolerance acceptance so it behaves correctly with
	underflow and overflow

	Also reverse sense of checkErrorAcceptable() so it now returns
	false on success and true on failure, as suggested by hmt. Change
	this in doTestVec() (which is where it is called) too.

	* tests/vectors/vector_support.h: 
	Remove #if 0'd shift_double() function

Mon Jul 27 21:55:04 1998  Jonathan Larmour  <[e-mail]>

Thu Jul 16 20:07:26 1998  Jonathan Larmour  <[e-mail]>

	* include/math.h, include/sys/ieeefp.h, src/misc/infconst.c:
	Remove union Cyg_libm_int_double from math.h, which was used to
	define infinity, and replace with use of
	Cyg_libm_ieee_double_shape_type from ieeefp.h

	That type (which is a union) is now reordered so that it can be
