screen-3.9.8 ported to cygwin

[rich-paul at rich-paul dot net]

I have made a naive attempt at porting screen 3.9.8 to cygwin,
and seem to have met with limited success.  The thing (seems to)
work, but when you close your last screen, it kills your console
window.  you also may have to mkdir /dev/pts  I'm afraid that I
can't remember the name, but screen'll tell you what file when
you first run it.  <G>

Here is the patch:

A remaining issue is that some of the commands in make install
fail, due to the .exe thing.  I tried to play with adding
@EXEEXT@ to Makefile.in (and AC_EXEEXT to configure.in) but found
that I started creating /opt/screen/bin/screen-3.9.8.exe.exe

At this point I decided to live with the error message. <G>

Are there porting guidelines that describe when/where/how to use
AC_EXEEXT?  


This is a Quick'n'Filthy[tm] patch.  It may electrocute you.  Don't
blame me.
