I would suggest that the flex package that's installed by Cygwin 1.5.3 is 
NOT valid.

I have just d/l'd and installed the version of flex straight from 
ftp.gnu.org, and it compiles everything exactly as before, pswrap and the 
old lex grammer file winprefslex.l.  Some of the header or support files 
must have been munged.  The version I used was:
$ flex --version
flex 2.5.31
