I think it would be better termed as a potential lawsuit by Unipress.

I hate it when people say things like this without backing it up. Could you
post some examples of the "standard" (I take it this means K&R) C code 
that xlc chokes on? I have a feeling it is mainly due to a lack of
understanding of the header standards (did you look at the BSD porting
document in /usr/lpp/bos?). GCC would be nice, but then you would loose all
of the optimizations performed by xlc (very significant from recent
comp.arch postings) that cannot be handled by gcc in its current form. GCC
is great for 680?0 code but it leaves much to be desired for the current
generation of RISC processors, especially the IBM one.
