bug#16444: grep -r fails with "Bad file descriptor" for mingw-w64

[Stephan T. Lavavej]

I've spent hours debugging this - it is definitely mingw/mingw-w64 specific. I 
don't really understand what's going on, but it appears that this is the same 
issue as http://lists.gnu.org/archive/html/bug-gnulib/2009-01/msg00370.html . I 
see that you committed 
http://lists.gnu.org/archive/html/bug-gnulib/2010-09/msg00230.html a while ago, 
but there are still uses of dirfd which always returns -1 for mingw.

Figuring out how to make this work is far beyond my area of expertise (if this 
involved crazy C++ templates I'd be right at home).

I know mingw is a second-class citizen, but if you or someone else who 
understands what gnulib is doing here could investigate, that would be 
wonderful for everyone on Windows who uses grep.

Thanks,
STL

Quite possibly it's specific to mingw, though.

Mingw is low priority for us,
but if someone like you with the motivation
and experience can come up with a patch
(ideally a patch to mingw), that might be nice.
