It depends.  The C standard header files are in /usr/include, and the
POSIX/SUS standard header files are where they belong.  Things like X11
and OpenGL and Motif are vendor-specific.

Why is one implementation better than the other?  Do you really -care- if
some header file included three levels deep from sys/time.sh is in
/usr/include/machdep or /usr/include/machine or
/usr/src/sys/include/platform or whatever?

If a given piece of software is so shoddy that it can only run on one or
two implementations of POSIX, barring some low-level dependency (a device
driver), it's broken software.  If it can run on Linux and it can run on
BSD, there are very few technical reason why it can't run elsewhere.

Political reasons are another matter entirely.
