That is not really a limitation, and pcc imlements enough of the
extensions as well (for C code). But we nowadays require C99 support,
so that rules out the most nasty stranglers upfront.

Most of this is abstracted away from the actual compiler in 
src/sys/sys/cdefs.h and everything relying on an extension not 
macro-magicalized there could be called a bug (worth a PR).

And of course we would accept patches that make it work with yet another
compiler. Are there any out there you are interested in especially?
