Mark, can you please make up your mind whether you are talking about
coding and design issues, or about ideology?  If the problem is xm.h
and the select vs gdb_select dichotomy, those are technical problems
for which I have no doubt that we will find good solutions.  In
particular, I firmly believe, based in no small part on my experience
of porting GNU software, that your fears of there being ``absolutely
no hope'' to have clean sources _and_ MinGW support--that these fears
have no real basis, because similar problems were solved elsewhere
more than once.

But if the problem is that you object in principle to having MinGW
support as part of the official codebase, then no amount of coding by
Daniel or anyone else will ever get your approval.

Which one is it?
