deprecated because they're in the application namespace
(e.g. '#ifdef linux' instead of '#ifdef __linux__').
This patch either corrects or just removes them if they are not
applicable to Linux.
The primary reason this is worth bothering to fix, considering how
obsolete a.out binary support is, is that the GCC build process
considers this such a severe error that it will copy the header into a
private directory and change the macro names, which causes future
updates to the header to be masked. This header probably doesn't get
