"I worked at a place where we ported our software to 20 different versions of Unix

If you're feeling odd or out-of-place, I'd like to point out that I had the exact same experience in the mid- to late-'90s.

Gcc also had the major advantage of compiling the same C on all of the machines. Yes, C was standardized and old at that time, but each compiler somehow found room to be slightly different.

Not to mention that the code it generated was pretty competitive in general with AIX's xlc and Sun's SPARC compilers.

P.S. Thanks for the licensing daemon flashbacks, dude. Thanks.
