cygwin gcc problem.

I'm trying to compile postgresql on Windows 2000. I've followed the directions accordingly.

When I run the "configure" script, and I get the following error message:

configure: error installation or configuration problem: C compiler cannot creat
e executables.

If anyone has any clues, I'd greatly appreciate the assistance.

Thanks,
Gary
