Comment # 2 on bug 1083902 from Andreas Schneider

The libtirpc detection in Samba doesn't work on openSUSE. It works just fine on
Fedora because the rpc headers are in /usr/include/tirpc. Currently it assumes
if the rpc.h header is /usr/include/rpc/rpc.h that glibc supports it. If it
isn't there it looks for libtirpc. But as SUSE decided to move the header to
its original location, the configure checks needs to be extended to cover this
correctly.
