It was done at some point, long time ago, but that was with DJGPP
v1.x. Since hooking hardware interrupts is quite different with DJGPP
v2, the old code won't work, and nobody (AFAIK) has rewritten it for
v2.
It shouldn't be too hard, though: you can use one of the available
packages for async communications that are in the v2tk directory on
SimTel.NET mirrors (check out section 22.3 of the FAQ for the exact
pointers).

I have successfully built GDB, both in plain DOS and in Windows 9X.
If you have LFN-related problems, the easiest way out is to set LFN=n
in the environment before building.
If this doesn't help, please describe the problems in more detail.
