Changeset #950 breaks building with other compilers than gcc

[andib]

wtkmmfc now has

#include <sys/fmutex.h>

which f.i. has

#include <386/builtin.h>

and probably more incompatibilities.

At least VAC3.65 does not like the gcc header files. Pretty sure VAC3.08 behaves the same.

At least xwlan/wlanstat needs the toolkit with vac compilers. Such compiler specific changes are a bad thing. At least proper compiler #defines in the sources would be cool. Of course the new functionality would only work with gcc but with defines it would not break others code.

Fully cross compiler compatible code would be even better of course.
