No worries :)
I was about to embark this mission on the NetBSD source anyway because
libgomp needs some OS-headers and I would like to keep me standalone GCC
pretty much clean (well as clean as those sources can be after I messed
with them :P )

I will see what I can do - I can't be that hard. After porting GCC,
Binutils, Newlib and the NetBSD kernel over the course of my studies
this is the final step.

I will document this and keep this thread posted.
Thanks a lot in advance!
