Actually, the problem is obvious.  The underscore in "CYGWIN_NT-5.1" 
made latex try to go into math mode.  By the way, I didn't look at the 
code closely, but I hope it doesn't try to detect cygwin by looking for 
"CYGWIN_NT-5.1" in the output of 'uname -s'.  I think the "NT-5.1" part 
of this reflects the underlying version of Windows.  So you should 
probably just test for an initial "CYGWIN".
