[opensuse-buildservice] Possible Bug in rpmlint/OBS?

I'm attempting to build devel:cloverleaf:Consort/athena and I keep running into the following error: [ 53s] ... testing for serious compiler warnings [ 53s] (using /usr/lib/build/checks-data/check_gcc_output) [ 53s] (using /var/tmp/build-root/.build.log) [ 54s] E: athena 64bit-portability-issue athena-toolbar.c:457 Everything compiles fine, but I run into that error, and the packaging fails. If I just build the tarball locally through the old ./configure && make and then check the build log, the error on athena-toolbar.c:457 isn't there. I'm running a current version of openSUSE Tumbleweed locally, and my buildtarget for OBS is also openSUSE_Tumbleweed What is going on here? Can somebody have a look at it?
