The other thread mentions that they provided the first unbundled C compiler back in 1989, closer to the standardization of ANSI C, which is probably no coincidence as many compilers had to be revised to support it and another reason why GCC became popular. It was not until they moved to SVR4 with Solaris that they removed the bundled one however, after gcc 2.0 was released I think.
