[ryandesign (Ryan Carsten Schmidt)]

apple-gcc-4.2 is of course the default compiler on Tiger. The libpixman port deliberately excludes that compiler with these lines:

platform darwin 8 powerpc {
    # apple-gcc-4.2 makes Tiger ppc fail to detect pthread support and then fail to build
    compiler.blacklist-append apple-gcc-4.2
}

These lines were added ten years ago to fix #44268. Back then libpixman was building with autotools; now that it uses meson the situation may be different. You can test removing that block and see if it builds and works.

Compilation starts, but fails here:

meson or ninja need an update to use the proper nm command, but the actual failure seems to be the OS which is so old that it does not provide _posix_memalign – but isn't it also in libgcc?

This seems to be in the end a duplicate of #68473 and #69146.
