Two corrupted libstdc++-v3 files in gcc-4.4.2.tar.gz (invalid file extension)

[Nicolai Josuttis]

Ah, interesting.
well the point is that I extracted the files
with WinZip (Version 9.0, build 6028) before I
started the built in a cygwin environment.
So, it's not a cygwin, it's a WinZip bug
(I can confirm that cygwin tar extracts the files
  with the correct extension).

Thanks for the fast feedback.
I will send a bug report to WinZp.
(and know I know why I was the first one having this
  problem).

Best
  Nico
