G4 with a 32bit ppc7450 CPU, running OS X Tiger 10.4.11 with Xcode 2.5 (GCC
4.0.1)
Cloned git repo & configured source
Configured it with the following flags (taken from config.log)
./configure --enable-languages=c --enable-shared --enable-long-long
--with-local-prefix=/Users/myusr/SandBox/gcc-trunk --enable-libssp
--enable-threads=posix STRIP_FOR_TARGET=/usr/bin/strip --with-dwarf2
--disable-libitm --disable-nls --with-gmp=/Users/myusr/pkg
--with-mpc=/Users/myusr/pkg --with-mpfr=/Users/myusr/pkg
--with-os-directory=darwin --with-arch-directory=powerpc --with-system-zlib
--enable-__cxa_atexit
--with-gxx-include-dir=/Users/myusr/pkg/gcc49/include/c++/
--prefix=/Users/myusr/SandBox/gcc-trunk --build=powerpc-apple-darwin8
--host=powerpc-apple-darwin8 --infodir=/Users/myusr/SandBox/gcc-trunk/info
--mandir=/Users/myusr/SandBox/gcc-trunk/man
System had dependencies installed for GCC 4.9 installed via pkgsrc.
Ran make

Also noticed that the compiler flags default to -m64 which won't work on a
32bit PowerPC host.
