autoconf 2.13 and failing tests.

[anthony stuckey]

        Long story, because I'm not actually sure how to even report this to
get it fixed.

        Autoconf 2.1.3 as shipped by Apple in MacOS X seems to include macros
that do not test for malloc() properly, causing test failures.

[localhost:/usr/bin] stuckey% ./autoconf --version
Autoconf version 2.13
[localhost:/usr/bin] stuckey% uname -a
Darwin localhost 1.3 Darwin Kernel Version 1.3: Thu Mar  1 06:56:40 PST

echo $ac_n "checking for working mmap""... $ac_c" 1>&6
echo "configure:2152: checking for working mmap" >&5
if eval "test \"`echo '$''{'ac_cv_func_mmap_fixed_mapped'+set}'`\" = set";
then
  echo $ac_n "(cached) $ac_c" 1>&6
else
  if test "$cross_compiling" = yes; then
  ac_cv_func_mmap_fixed_mapped=no
else
  cat > conftest.$ac_ext <<EOF
#line 2160 "configure"
#include "confdefs.h"

[..]

#ifdef __cplusplus
extern "C" { void *malloc(unsigned); }
#else  
char *malloc();
#endif



        The problem is that the char* malloc defined here conflicts with the
void* malloc defined in /usr/include/stdlib.h.  Thus the code sample does
not compile, and the test is considered failed.

        Does this need to go into the Darwin bug tracking database, the
Autoconf bug database, or what?
