This is a completely new directory for DJGPP I created. It contains no 
files from my previous install.
I have one dir  on my C:\ as DJGPP and my F:\ drive as DJGPP_205 and 
just set my PATHs and DJDIR accordingly.

This is Quake 2, and because the entire game dll is statically linked to 
the binary now it's a rather large project.
If you hit those COFF limits will it hurt things?  I will try this 
bfdsymify.

After these issues are sorted out I would still like some information on 
it.  We tried an old project, DLM (http://aaganichev.narod.ru/djgpp/), 
and during runtime it would
give us this:

DLM -> Exiting due to signal SIGSEGV at
0x0014f59d SYM: _dos_lockmem+0x9 DLM: q2.exe [0xf5000]
possibly because of undefined reference to symbol ‘___djgpp_base_address’

DLM call frame traceback :
0x0014dcaf SYM: _Sys_PageInProgram+0x37 DLM: q2.exe [0xf5000]
0x0014e1c4 SYM: _main+0x18 DLM: q2.exe [0xf5000]
0x0000774e
0x00008b6e

But anyways, one issue at a time here :)
