I don't think they ever intended anyone to use it with wchar-less systems. 7-Zip is heavily oriented towards Windows, and p7zip is heavily oriented towards POSIX. And just to be super obvious here, DJGPP is neither, thus it's much harder (as this code is not portable enough to easily work for us).

7zdecode is pure C, but p7zip (7z,7za,7zr) is C++. I don't know where you're getting your DJGPPs from, but 2.7.1 (presumably 2.7.2.1 ??) is way too old.

Of course there's a way, but sadly nobody cares (or at least not the ones who wrote the stuff). That's their prerogative, but unless we have the time and skill to fix it (and I certainly don't), then we're out of luck.

Latest /current/ is GCC 4.7.3 while /beta/ has 5.2.0. They are currently (no pun intended) halfway intending to remove /beta/ and just put DJGPP 2.05 (DJDEV205.ZIP, etc.) into /current/ .
