* sysdeps/generic/dl-environ.c (unsetenv): Rewritten using strncmp,

	no longer wrongly matches arbitrary prefixes of NAME.
	Reported by Jakub Jelinek <jakub@redhat.com>.

2002-09-11  Jakub Jelinek  <jakub@redhat.com>

	* posix/bug-regex11.c (tests): New array.
	(main): Rewritten to run more different tests.

	* nscd/Makefile (CPPFLAGS-nscd, CPPFLAGS-nscd_conf, CPPFLAGS-dbg_log)
	(CPPFLAGS-connections, CPPFLAGS-hstcache): Variables removed.
	Instead, catch all of $(nscd-modules) via cppflags-iterator.mk.
