* aclocal.m4 (LIB_AC_PROG_CC): Moved here from configure.in.
(AC_DEFINE_NOAUTOHEADER): New - work around bug in autoheader. * configure.in: Call AC_C_INLINE and AC_C_CONST. Use three argument form of AC_DEFINE in dummy definitions block. Use AC_DEFINE_NOAUTOHEADER for real definitions of things defined in dummy block. Preload cache variables instead of bypassing tests, where possible. * acconfig.h: Removed. * xmalloc.c (xmalloc_failed): New function, does error reporting on failed allocation. (xmalloc, xcalloc, xrealloc): Use it.
