Now yes, but FreeBSD needs an iso c'99 compiler and source code is 
iso oriented, not gcc, afaik gcc hacks and code that only compiles on 
gcc can't be commited, there's a mailing list for iso99 compatibility 
checks. gcc is one of them, but there are others. 9.0-CURRENT uses 
llvm but in theory you can use anyone, even tcc.
