warning reported from running ./configure script

[Nash, Brian]

Hi,

On running the expat configure script, it produced a warning and asked
to email it in. So its below.

The issue seems to be with the cygwin -mno-cygwin compiler option, since
if I omit it, the script completes without a problem.

Let me know if I can supply any more details.

Command executed:- 

cygwin-3.00$ ./configure --build=i686-pc-mingw32
--prefix=/cygdrive/j/expat CFLAGS='-g3 -O0 -mno-cygwin'

Output from script:-
