If you want to get around this bug, you could correct the version parsing,

change in

File "d:\programs\python25\lib\distutils\cygwinccompiler.py", line 424, in
> get_versions
>     ld_version = StrictVersion(result.group(1))

to

  ld_version = StrictVersion(result.group(1).rsplit('.',1)[0])


see version problem

>>> from distutils.version import StrictVersion
>>> StrictVersion('2.18.50.20080625')
Traceback (most recent call last):
  File "<pyshell#246>", line 1, in <module>
    StrictVersion('2.18.50.20080625')
  File "C:\Programs\Python25\lib\distutils\version.py", line 40, in __init__
    self.parse(vstring)
  File "C:\Programs\Python25\lib\distutils\version.py", line 107, in parse
    raise ValueError, "invalid version number '%s'" % vstring
ValueError: invalid version number '2.18.50.20080625'
>>> StrictVersion('2.18.50.20080625'.rsplit('.',1)[0])
StrictVersion ('2.18.50')



But, see my other message, try without cygwin. I usually don't have
any problems building scipy with mingw.
