About nss: This only matters if you use static binaries. Static
binaris, which dlopen NSS modules, only works with the glibc they
are linked against. Everything else is known that it can fail.

nis: This changes where only for nss_compat. nss_compat does not have
any impact on nss_nis or nss_mysql. This is impossible. So the problem
is somehwere else, but it cannot be my change to nss_compat.

About nss_compat: Yes, there is a bug which prevents getspnam from
correct working with shadow over NIS. The fix is trivial:

For glibc CVS, I will make another patch with some more code
