acinclude.m4 (GLIBCPP_ENABLE_LONG_LONG): Check for lldiv_t. 


2000-12-05  Benjamin Kosnik  <bkoz@haight.redhat.com>

	* acinclude.m4 (GLIBCPP_ENABLE_LONG_LONG): Check for
	lldiv_t. Allow the use of os-specific defines while checking for
	long-long functions by the inclusion of os_defines.h.
	* aclocal.m4: Regenerate.
	* configure.in: Add comments.
	* configure: Regenerate.
	* acconfig.h: Add _GLIBCPP_HAVE_LLDIV_T.
	* config.h.in: Regenerate.
	* config/os/gnu-linux/bits/os_defines.h: Fix typos and
	duplications in comments.
