I'm unable to build Phar, and here's the [buggy] compiler:

water:/tmp philip$ gcc -v
Using built-in specs.
Target: i686-apple-darwin8
Configured with: /private/var/tmp/gcc/gcc-5363.obj~28/src/configure --disable-checking -enable-werror --prefix=/usr --mandir=/share/man --enable-languages=c,objc,c++,obj-c++ --program-transform-name=/^[cg][^.-]*$/s/$/-4.0/ --with-gxx-include-dir=/include/c++/4.0.0 --with-slibdir=/usr/lib --build=powerpc-apple-darwin8 --with-arch=nocona --with-tune=generic --program-prefix= --host=i686-apple-darwin8 --target=i686-apple-darwin8
Thread model: posix
