On my iBook G3 Indigo (PowerPC 750CXe) running OSX Tiger 10.4.11, XCode 2.5, MacPorts 2.5.4, and `sudo port -v install git gcc7 gmake wget bash`, trying to build Crypto++ resulted in this error: ``` $ export CXX=/opt/local/bin/g++-mp-7 $ gmake deps Using testing flags: -Wa,-q g++ -Wa,-q -DCRYPTOPP_DISABLE_ALTIVEC -fPIC -pipe -DCRYPTOPP_DISABLE_ASM -MM *.cpp > GNUmakefile.deps $ gmake Using testing flags: -Wa,-q g++ -Wa,-q -DCRYPTOPP_DISABLE_ALTIVEC -fPIC -pipe -c cryptlib.cpp /opt/local/bin/as: can't specifiy -q with -arch ppc gmake: *** [GNUmakefile:1573: cryptlib.o] Error 2 gmake: Target 'default' not remade because of errors. ``` The Clang integrated assembler seems to be used for targeting modern Intel instruction sets, because the default GCC Assembler (v1.38) is too old. Change that logic to not be activated on PowerPC systems. For reference, on my system: ``` $ /opt/local/bin/as -v < /dev/null Apple Inc version cctools-921, GNU assembler version 1.38 $ /opt/local/bin/as -qv < /dev/null /opt/local/bin/as: can't specifiy -q with -arch ppc ``` and: ``` $ /usr/bin/as -v < /dev/null Apple Computer, Inc. version cctools-622.9~2, GNU assembler version 1.38 $ /usr/bin/as -qv < /dev/null /usr/bin/../libexec/gcc/darwin/ppc/as: I don't understand 'q' flag! Apple Computer, Inc. version cctools-622.9~2, GNU assembler version 1.38 ```

OK, my PowerMac is back up. I'm testing OK with the patch applied. Thanks again. I'm wondering if we should add a feature test for it, like Clang and |
