Impatient, are we?  Most of the speed complains about gcc tell about 
compilation times like 10 minutes or so...

Seriously, if you want to test the speed of compilation on your system,
don't start with such small programs, where the overhead of the multi-pass
compiler like gcc is the main factor.  Try compiling larger program, say a
few hundreds of lines and test against the table in the FAQ.

There is no FAQ for v2.0 yet; the suggestions in the old FAQ aren't all 
valid for v2.  However, on your machine, there isn't much you can do.

What memory settings did you put on the .pif file for DOS box?  What does 
go32-v2 print when invoked with no arguments in the DOS box?

Is DJGPP installed on a networked drive?  If not, how is the fact you use 
Novell relevant?

I would suggest enlarging the size of the disk cache, even if it means to
disable the RAM drive completely.  If you use SmartDrv 5.0 (the one which
comes with DOS 6.x), be sure to use its /N switch to make it a true
write-back cache.
