It is still Free, is it not? What host OS are you trying to build atop?
Are you just worried that it won't rebuild cleanly? A lot of stuff
indirectly relies (too) heavily on NTVDM, e.g. LFNs.

Okay, but I haven't looked closely myself. Should I? What
functionality does the prebuilt library lack that you need?

I'm sure someone can, but I don't know what's wrong with just using
pre-existing binaries. Then again, I understand wanting to be able
to rebuild various DJGPP things, but it's not always easy.

DJGPP is basically only for DOS. Even under Win9x or NTVDM, there were
no DOS APIs for such a thing.

It's possible that DR-DOS 7.03 had some APIs, but nobody cared enough
to support it with DJGPP. Nine years ago I did submit a sloppy patch
for dosexec.c to use int 2Fh, 2707h, but that only worked with DR-DOS'
TASKMGR loaded. It did work, I think, but I never used it much, plus
I don't even use DR-DOS anymore. And nobody else seemed to care.

Honestly, something like DOSEMU is now probably considered a better
supported Free solution for multitasking DOS stuff.
