What if MAP_FAILED is an enum or const int? #ifndef won't catch that.
POSIX doesn't state MAP_FAILED is a macro, just a "symbolic constant".

It would usually work though.

Of course we can have configure.ac check it, but I wanted to avoid
polluting configure.ac with contrib/* checks and contrib/* with #include
<config.h>.
