on CentOS 5.10 x86_64 using following command

rpmbuild -ta cups-2.0b1-source.tar.gz --without libusb1 --without systemd

I also just tried removing the -Wsign-conversion and get the following error

OK, needed a configure check for the GNU TLS function (new in 3.0), and added a configure check for -Wsign-conversion (although that warning has been around for a LONG time...)

Source changes attached.
