Bug #1203649 was reported against dragonegg, which is tied to the
specific version of gcc it is built against, because it uses the gcc
plugin interface. EL7.1 has a newer gcc, so dragonegg has to be
rebuilt. I did a new build (fedpkg build from epel7 branch), but it
still built against gcc from EL7.0. Is there a way to build EPEL
packages against EL7.1?
