It is important to realize that the compiler in djgpp is *big*.  The
files in the bin directory are stripped, so what you see is all code
and data, and must be read from the disk.  Also, go32 must be loaded
for each binary.

I recommend a small ramdisk for gcc's temporary files (TEMP=) and at
least two meg of disk cache, plus at least one or two meg of
*available* memory for go32 to use.  Running go32 gives you memory
availability information.
