Created attachment 197355 [details] patch This patch removes -Wno-unused-command-line-argument compiler flag from sources. It's not supported by base GCC and using it causes build failures. If this approach is not acceptable, we could switch to using newer compiler (GCC from ports via USES=compiler:c++11-lang), but removing -Wno-unused-command-line-argument causes less overhead when building this ports on powerpc64. Tested on powerpc64 and amd64.
