Hi all,

I have written a small (<64K) program which I want to execute as
quickly as possible. 

So far, the best performance I've got in the djgpp environment is
from the following:

	gcc -m486 -O2 wibble.c

i.e. compile the program "wibble.c", using 486 specific instructions,
and level 2 optimization.

I imagine that there are other optimization options to gcc that can
improve performance considerably.

Any guidelines?

Thanks in advance,
Tom King
