I just upgraded my cygwin installation to the latest versions. Which
seems to include
GNU ld (GNU Binutils) 2.18.50.20080523
and
GNU dllwrap (GNU Binutils) 2.18.50.20080523

It seems that their version notation is now Major.Minor.Micro.Date
The problem is that in 'cygwincompiler.py' it does:

        result = re.search('(\d+\.\d+(\.\d+)*)',out_string)
        if result:
            ld_version = StrictVersion(result.group(1))

Which matches the full version string. However "StrictVersion" only
supports A.B.CdE formats. So the .Date breaks the parser.

My workaround was to change the regex to be:
        result = re.search('(\d+\.\d+(\.\d+)?)(\.\d+)*',out_string)

So it will still match an unlimited number of '.DDD' as it used to, but
now it only preserves the first 3 to pass to StrictVersion.

This may not be the correct fix, as a better fix might be to use
something else instead of StrictVersion (since these version numbers
explicitly *don't* match what StrictVersion expects.)

Quick patch that changes the regex

Do you need the (\.\d+)* trailer in the regex at all?

Not sure. The actual revision is:

2.18.50.20080523

The code used to allow lots of version numbers, and I didn't know if we wanted
to require that or not.

Certainly just changing * => ? is a simpler fix. And since we don't end with $
or anything, it should still match.

This seems to be the same as #2234.
