They claim at the homepage that they improved some stuff. My experience is that a single person when improving a tad at such compilers can really get out a lot of speed; if a guy like me spends a few months improving GCC it's of course faster at specific processors than any other compiler, provided the codes are quite generic and not in some sort of benchmark which they analyzed to death.

GCC is such beginnerslevel that it's rather trivial to improve it. So if someone claims he has done that, and some NCSA logo is on top of the project, i take that serious unlike you, even though odds were not big here.

Now you can forever post that something ain't gonna work at all, but if they provide a few binaries, it's just as easy to just install it, and have it run.

then you can compare the actual binary with gcc and see they just cut'n pasted an oldie GCC version.

Which is what i did do.

that's hard evidence. Just guessing that is usually ok, but not how you're supposed to deal with it if there's a NCSA logo on top of such a project.
