--- Comment #7 from Martin Sebor <msebor at gcc dot gnu.org> --- I test my warning changes with binutils and --enable-targets=all. But that apparently doesn't compile all source files, and I don't have a cross-build setup in place (or the resources to do it). If someone who already does cross-builds could periodically post results to gcc-testresults (or report bugs), or if we could get these going in Jeff's buildbot, that would help catch the problems in those before either package is released.
