2008-08-12 Paolo Carlini <paolo.carlini@oracle.com>

	* configure.ac: Run unconditionally GLIBCXX_CHECK_INT64_T and
	GLIBCXX_CHECK_C99_TR1; remove sigsetjmp and mmap checks (unused).
	* crossconfig.m4: Adjust; remove HAVE_GETPAGESIZE defines (unused).
	* configure: Regenerate.
	* config.h.in: Likewise.

	* acinclude.m4: Minor formatting fixes.
