Hi Camm.

Thanks; I was pleased to get them in.  I built working versions of both
Maxima and PCL with the minimal changes currently in CVS.

Instructions for Mingw32 are in the file "Readme.mingw" which, for
historical reasons, preserves the original text at the end, marked as being
out of date.

I noticed I had ignored other platforms after checking in that particular
change, but I decided against further specialising it until I got feedback
about other platforms.  My suspicion is that -O2 will be fine on most
platforms, especially if they use gcc as their C compiler, and even more so
if they are IA32 architectures.

You will note that I did not make any changes related to stack checking for
the time being, as the code in CVS seems to at least work superficially.
This will probably change as what is ther at present seems arbitrary.

Likewise, after a bunch of trial and error experiments, I did not put the
ASCII nul copying into "cmpmain.lsp", as it seems to be unnecessary on
Mingw32.

(The reason I put it in last week, was that GCL was built that way and I was
trying to reproduce a known working compilation method.)

I intend to experimentally build GCL without the manual null concatenation
done by the makefile (as opposed to that done by "compile" and
"compile-file" from the REPL).

I would suggest that users of other platforms experiment with the need for
that stuff too.

Cheers

Mike Thomas.
