OK, so I think it would be best to #define PAGEWIDTH 12 in your
gnuwin95.h file. Even with this value, DBEGIN is still way off.

No files unfortunately. If you have the program 'tee' you can
./configure | tee config.out. Alternately, just ./configure
>config.out.

I'm rather mystified by this design too. I think it may just be an
age thing. In any case, we might want to play with this idea in
2.5.0. I think its too big a change for 2.4.1, which I would like to
get working with as few changes as possible on as many platforms as we
can. Personally, I think the whole thing needs a bit of a rewrite,
but we have to be careful, and time our changes properly.
Take care,
