I didn't met any problems to build gdb-4.17 for Linux. I used sources of gdb-4.17 
also to rebuild RHIDE under Linux. All worked Ok

For DJGPP things were much worse (I tried only gdb-4.16.86 in March). After some
hacking as target i[3456]86-pc-msdosdjgpp was not supported. I took some files from 
port of 4.16 and after some more hacking and I suceeded to build it but it still was 
seriously broken:
   - viewing call stack (bt) was broken. To force it to compile I had to take
     some parameters from ceiling and of course they were wrong. I simply don't know
     what I must put there...
   - Previously I was not able to get normal reaction to SIGINT in DJGPP port of
     gdb-4.16 when I built it from sources (The process I'm debugging does no
     more exist when I'm getting next gdb prompt after SIGINT, this is not so
     in binary archive built by Robert [gdb416b.zip] and in binaries I have built
     under Linux

I didn't try to mess with development snapshots in DOS more after March.

One suggestion. I think we should get rid of these batch files. I think
that the way that is used in ports of gcc-2.8.0 and gcc-2.8.1 is better:
   additional bash scripts that sets needed environment parameters and
   invokes configure and make.

Perhaps it is not so terrible to ask poeple who want to build some packages
from sources to install bash
