2000-06-19  Raja R Harinath  <harinath@cs.umn.edu>

	* src/Makefile.am: change @WERROR@ to $(WERROR) so that this can
	be overridden on the command line for individual files.

2000-06-19  Benjamin Kosnik  <bkoz@soma.redhat.com>

	* acinclude.m4 (GLIBCPP_CHECK_MATH_SUPPORT): Can't use
	AC_LANG_CPLUSPLUS as this tries to link in libstdc++, Which we are
	building. Use -x c++ instead, which does not attempt to link
	libstdc++.

* acinclude.m4 (GLIBCPP_CHECK_MATH_SUPPORT): Can't use
AC_LANG_CPLUSPLUS as this tries to link in libstdc++, Which we are
building. Use -x c++ instead, which does not attempt to link
libstdc++.
* acinclude.m4 (GLIBCPP_CHECK_LINKER_FEATURES): Actually check for
not coring when we hit a try/throw block, which was the problem
with the linker support...
* docs/17_intro/contribute.html: Add bits about getting to the LWG
issues pages.
* docs/documentation.html: Rename link to make more accurate and scary.
