aclocal.m4 (AC_FUNC_MMAP_ANYWHERE): Completely rewritten. 

2001-01-11  Zack Weinberg  <zack@wolery.stanford.edu>

	* aclocal.m4 (AC_FUNC_MMAP_ANYWHERE): Completely rewritten.
	Now defines HAVE_MMAP_DEV_ZERO and/or HAVE_MMAP_ANON depending
	which you have.
	(AC_FUNC_MMAP_FILE): Don't AC_REQUIRE AC_FUNC_MMAP_ANYWHERE.
	* configure.in: Set GGC to ggc-page if any of mmap_dev_zero,
	mmap_anon, and valloc is available.
	* ggc-page.c: Restructure ifdef logic to match new autoconf
	spec.  Don't throw away the test page in init_ggc.

	* configure, config.in: Regenerate.
