Test with path64 to see what the effect would be for not using gcc. We call cc142 directly and it'll give you an indication of how much slower open64 is for compilation time by doing that. Also I can probably get you psclang this/next week to test with. It remove cc142, libspin and wgen. This should likely save some time as well and possibly bring the compile times down to being competitive with gcc.
