Unfortunately, just because the header is there doesn't mean anything will actually work :(. Also, the check is based on the host vendor/os for now. Yes, it's rather lame but it will do for now. With this, QF will build on an almost fresh ps3toolchain install. Only two "fixes" are needed: o In $PS3DEV/ppu/powerpc64-ps3-elf: ln -s ../include sys-include o libsamplerate cross-built and installed.
