Our application has been using AC_FUNC_MMAP to test for a working
mmap(). This macro is now described as:
AC_FUNC_MMAP
If the mmap function exists and works correctly, define HAVE_MMAP.
Only checks private fixed mapping of already-mapped memory.
Notice that it is only checking private fixed mapping. This is just
one use of mmap, and not even a recommended one.
It seems to me that there should be one macro to test this ability to
handle private fixed mapping (e.g. "AC_FUNC_MMAP_PRIVATE"), and
another macro to test the ability to properly access and update a file
via mmap() ("AC_FUNC_MMAP_FILE").
