Re: [bug-gnulib] Re: [PATCH] mmap-anon.m4: use proper macro & condition

[Mark D. Baushke]

Hi Folks,

I have not seen any discussion or commit on this patch suggested by
Moriyoshi Koizumi <address@hidden> (originally submitted to the
bug-cvs list and forwarded by me) which allows MacOS X (10.2.x and
10.3.x) to properly be able to '#define HAVE_MAP_ANONYMOUS 1' along with
'#define MAP_ANONYMOUS MAP_ANON' ...

This lets us get rid of the configure lines:

cat >>conftest.$ac_ext <<_ACEOF
/* end confdefs.h.  */
#include <
#include <sys/mman.h>
#ifdef MAP_ANON
    I cant identify this map.
#endif
>

_ACEOF

and replace them with

cat >>conftest.$ac_ext <<_ACEOF
/* end confdefs.h.  */

#include <sys/mman.h>
#ifdef MAP_ANON
    I cant identify this map.
#endif

_ACEOF

which at least is valid C code.

Please install it in GNULIB.

        Thanks,
        -- Mark
