From Quake Wiki
FrikQCC started just before the Quake engine source release last year. Based off of Johathan Roy's FastQCC, I tried to bring new features to the code to make Quake more appealing a language to high nosed programmers that said it wasn't a 'proper language'. Early in 2000, JP Grossman released qccx, which proved to be a major turning point in frikqcc. Though most of his engine data hacking features leave me a bit dry, the optimizations really got my mind working in overdrive. The result is the below.
[Updated! Version 2.6!] This is a customized version of qccx. It supports: goto, labels, static variables, new optimizations, compiler warnings, and many other features.
