Many configure scripts fail because GCC emits a pointless diagnostic
whenever -I/usr/local/include is specified on the command line.  Viz.:

configure:2826: checking for ANSI C header files
configure:2839: /arch/sparc64/hosted/bin/gcc -E  -I/usr/local/include conftest.c
 >/dev/null 2>conftest.out
cpp0: warning: changing search order for system directory "/usr/local/include"
cpp0: warning:   as it has already been specified as a non-system directory
configure: failed program was:
#line 2831 "configure"
#include "confdefs.h"
#include <stdlib.h>
#include <stdarg.h>
#include <string.h>
#include <float.h>

This appears to be a bug in autoconf 2.13, which is fixed in 2.52, but
there are still a large number of autoconf 2.13 scripts which we will
need to be able to run for the forseeable future.
