I don't doubt he is. :)

I still haven't found the time to try it out. :(

2.7.x didn't include optimization, didn't it? But I read it was fast. And I recently came across an optimizier from that era (Linux though).

I don't know about DOS, but 2.7 might be still buildable on modern Linux. I successfully built 2.8 and 2.9 recently. Although they don't like some of the recent glibc headers. But they work. C compiler... C++ doesn't. Although you need to build GCC 3.x first. GCC 4 won't work.

He did great job with what he did by now. It just needs some tweaking and it might become an interesting alternative. :)

DJGPP is great though. But it doesn't hurt to have another freely available option. :)

I'm mostly a Linux guy, so I don't get much time to play with DOS stuff. But I do from time to time. I'm a bit of retro enthusiasist (that also includes old Linuces/Unices and also *dows). :)

I did setup a functional DosEMU setup with DJGPP and OWatcom this time, so I do get around more than before.
