Update. 
2000-08-01  Ulrich Drepper  <drepper@redhat.com>
	    Joseph S. Myers  <jsm28@cam.ac.uk>

	* math/tgmath.h: Make standard compliant.  Don't ask how.

2000-07-04  H.J. Lu  <hjl@gnu.org>

	* elf/Makefile ($(inst_slibdir)/$(rtld-version-installed-name)):
	Use $(do-install-program) instead of "$(INSTALL_PROGRAM) $< $@.new".
	($(inst_slibdir)/$(rtld-installed-name)): Use $(make-shlib-link) only.

2000-07-30  Maciej W. Rozycki  <macro@ds2.pg.gda.pl>

	* include/features.h (_XOPEN_SOURCE): Update the explanation.
	(__USE_LARGEFILE): Add an explanation.
	(_POSIX_C_SOURCE): Define to 2 only if _XOPEN_SOURCE < 500.
	(__USE_XOPEN2K): Define whenever _XOPEN_SOURCE >= 600.

2000-08-01  Ulrich Drepper  <drepper@redhat.com>

	* libio/Makefile: Enable exception handling for genops, wgenops,
	fileops, and wfileops.
