      Description

      Build of qpid-proton-0.3 fails on s390 and ppc(64) with an error from gcc

      ...
      ./usr/bin/cc -Dqpid_proton_EXPORTS -O2 -g -pipe -Wall -Wp,-D_FORTIFY_SOURCE=2 -fexceptions -fstack-protector --param=ssp-buffer-size=4 -m31 -march=z9-109 -mtune=z10 -fPIC -I/builddir/build/BUILD/qpid-proton-c-0.3 -I/builddir/build/BUILD/qpid-proton-c-0.3/include -Werror -Wall -pedantic-errors -std=c99 -o CMakeFiles/qpid-proton.dir/src/messenger.c.o -c /builddir/build/BUILD/qpid-proton-c-0.3/src/messenger.c

      cc1: all warnings being treated as errors

      Probably the understanding of the function by gcc differs between x86 and s390 or ppc
      gcc-4.7.2-8.fc18.s390
      gcc-4.7.2-7.fc18.ppc

      Version-Release number of selected component (if applicable):
      qpid-proton-0.3-1.fc18
