Restrict overmatching MACH ifdef to only trigger on OSX and Mach #3

Zopolis4 wants to merge 1 commit into rbsheth:master from Zopolis4:master

Hurd also uses Mach, but does not have the same behavior as OSX in this area.

Such guard is clearly not enough, since not only Apple uses Mach as a kernel. 
This should be replaced by #if defined(__MACH__) && defined(__APPLE__)
