Weekly updated cvs sources of DJGPP from
cvs.delorie.com. Look at the time of the file TIMESTAMP to see when it
was last updated.
Looking for the trusty old C compiler gcc 2.7.2.1? You can find it
here. There's also gpp 2.7.2.1 for completeness
but I don't recommend that you use it for C++ programming because it
wasn't very good at the time and the language has changed much since
then. Plus Objective C, also for completeness.
