Please ignore the patch sent in the previous email, it was missing the
autoconf bits. The correct patch is now attached to this email.
I have copied the macros from the libX11 example and I have verified
that the HASGETRESUID/(HASSETUGID) are defined during the build on F15 -
still, I would prefer if someone could double check it..
The good thing is that this explains why Michal was using the fallback
code when testing, bonus is that this got tested properly, otherwise it
might not have.
Sorry it took so long to get it into shape..
