Do you mean apple-gcc-4.2?  macports-gcc-4.2 is *very* old and AFAIK only compiles on Tiger.  gcc43 and later should work on Leopard and newer.  apple-gcc42 should work on Tiger and newer.

Nobody's really interested in llvm-gcc at this point in time.  If it doesn't work, try with clang and dragonegg.  llvm-gcc is pretty much dead.

That's a bug in myth's build system.  They're compiling ObjC++ code ( with -std=c99, which is not valid.  You should either fix it or report the bug to myth developers to fix.  That issue is probably ignored by gcc.
