My experience was different. I'm used DOSEMU-0.97.4. Borland C++ 3.1 IDE runs
under it terribly slowly. gcc-2.8.1 for DJGPP runs much better (of course in DOSEMU
not so fast as under Win95). Have to reinstall Linux from scratch recently
so didn't tried latest versions. Haven't installed DOSEMU after that at all.
I used LREDIR to get access to DOS partitions (really mounted in Linux as
VFAT ones).
Of course there are problems with DJGPP under DOSEMU. Once tried to
build DJGPP port of gcc-2.8.1 from DOSEMU and almost succeed
(DOSEMU didn't like filenames with extension .null)
