I thought I sent my previous message to djgpp list, but only to you... 

I also did a small test.  With default settings (4MB DPMI, etc.) of 
an OS/2 Warp DOS session, djgpp's regular gcc didn't crash even after 
30 recompilations in one window.  So, I assume that djgpp does not 
have any problems with OS/2 Warp's DOS session.  FAQ listed the crash 
problem (#2.2), but I think the problem has been fixed in OS/2 Warp.

My djgpp version is 1.12.maint3.  I think djgpp's memory requirement
has been also improved.  I recall that 4MB DPMI was not enough for 
old djgpp (5MB required), but now djgpp can run with small memory.
