glibc 2.3.1 patch

[Ove Kaaven]

The newest glibc in debian unstable, 2.3.1-8, does not seem to want to
export h_errno anymore, which causes a link failure. (and netdb.h now
defines h_errno to *__h_errno_location() regardless of whether
_LIBC_REENTRANT is defined or not.) So I used this hack in WineX, not sure
if it would be anywhere close to the right approach, if the right approach
presumably wasn't to remove this file entirely.

Log Message:

Make Wine compile on glibc 2.3.1.
