Old 8086 version of pcc spotted (cross-compiles to DOS) (Miscellaneous)

Only very very barely.

QEMU is fairly hard to build on Win32, or at least pre-built binaries aren't as easy to come by anymore, apparently. But I usually just use VirtualBox, "good enough", these days.

Nah, I run Linux a lot on that other machine (triple boot). It's just I hate POSIX-only code, it's so ugly. If I write DOS-only code, I'm an idiot, but they write Linux-only code and are geniuses, go figure.

Nothing big. Just the fact that the compiler itself isn't LFN aware after all this time can't be a good sign. (I guess we should be running Win32-hosted under HX?)

No, haven't tried, didn't seem worth the effort, maybe only for more independence or looser licensing or whatever. GNU ld may (in theory) build with LCC + POSIX libc (aka, DJGPP libc 2.01 he used), but I haven't tried.

P.S. (next post) You're right, ALINK supports some form of COFF, but I'm not sure if that's the DJGPP variant or (more likely) only Win32 PE/COFF, which differs in some incompatible ways (e.g. reloc handling). Actually, ALINK is old, buggy, and long abandoned, so I'm not sure how robust it is. (But better than nothing, I guess.) If you really just want a totally independent toolset, try CC386. At least that (supposedly) can build itself. OpenWatcom can too but not on DOS (AFAIR) though one guy halfway tried a few years ago.
