I have this PS/1 486-SX50 setup with DJGPP V1.12 and 2.03.  I'm starting out 
with 1.12 so I compile X. I have my old Dell Latitude Cpia configured the same 
way and both are on the network. So far, I think have environment configured 
correctly on the 486 because I can compile successfully, but I'm not sure 
about a few things pertaining to go32 and emu387 environment settings. I got 
run-time errors until I SET the following:

SET 387=YES

I have go32s environment set correctly with "emu=d:\djgppv1\emu387". So I 
compiled ~/demos/xeyes to test the environment again. Xeyes compiles and runs 
on a remote display with the exception that there are no eyes displayed in the 
window. My go32=ansi right now. ~/dvx/Xeyes.exe that came with the DV/X 
distribution displays ok. I guess it was compiled with WATCOM, so its makeup 
is different than the binary which DJGPP is producing from source. Right? 

Q: Do I need to install ansi.sys or change the display driver to something 
else like VGA.GRD?

I assume that emu387 is working otherwise I would have compile problems.

Q: Does anything in the ~/djgpp/emu387 need to be pre-compiled? There are no 
binaries in the directory right now. It's all source.

I think I might have answered my "ansi" driver problem while writing this. Any 
comments and answers would be appreciated.
