Rev 1.31 of src/nparse.lisp breaks windows build of CVS HEAD

Vadim,

Thanks for investigating. Looks like the situation is a little messy.
I don't see any clear indications.

Maybe a way to make some progress here would be to figure
out why Maxima 5.10.0 + GCL 2.6.8 doesn't work as expected
on Windows (and help the GCL project fix SI::NEWLINE if
necessary) and then revert the attempted bug fix in r1.31 src/nparse.lisp.

That would imply GCL 2.6.8 or later is required to compile Maxima
on all platforms. Since most people are using the precompiled
Windows package, I don't see a problem with that.

All that is easy for me to say, of course -- I don't have a Windows
build environment.

All the best
