You should set the TMPDIR environment variable.  Note that detailed
instructions about optimizing DJGPP setup are included in the DJGPP FAQ
list, section 3.9; please read it.

If you have enough place there, yes, but it isn't required, strictly
speaking, and AFAIK will only have significant effect if you need the
first compilation to be as fast as possible.  It is better to set up a
large disk cache, which will then service DOS I/O calls out of memory
anyway; then you don't need to decide what you should and what you
shouldn't copy to RAM drive.
