Here's another interesting note.  I've got a real-time
graphics program (~65k lines of source code) that I've
compiled and executed with the following results:
  DJGPP 1.12m4 with GRX 1.03 :  18 iterations/sec.
  DJGPP 2.0beta4 with GRX 2.0:  8 iterations/sec.
All on a 486/66.

I've tried the V2.0 with both the MS DPMI and CWSDPMI
with the same performance results.  The newer versions
are giving 1/2 the performance of the V1 programs.

Any ideas?
