I notice that you seem to have no warning flags at all on your command line. That's probably because when --disable-build-warnings is passed, we don't append any of the -W* -Wno-* flags. But in that case, we should still append the -Wno-* flags... So it sounds like an issue that should be fixed in warning.m4. I'd suggest using --disable-werror instead: you'll see warnings, but they'll be non-fatal. Simon
