I would doubt that MSVC does wrong optimizations wrt. restrict.
At least I haven't heard about it before (and none of my previous
arguments dealt with this topic).

If your program does not make use of mmap(MAP_FIXED), then I assume
that you could get away with AC_CHECK_FUNC([mmap]) rather than using
AC_FUNC_MMAP. See the manual on details of this macro.

There is no real memory in most if not all unix-like systems, either.
But this does not have much to do with the above, so never mind.
