    CARD32 redMask B16, greenMask B16, blueMask B16;

This is clearly a bug, the B16s should be B32 instead.

But to answer the larger question, the bitfield stuff is only there to
help *client-side* 64-bit architectures.  If the server even comes remotely
close to building on a 64-bit system, then it's simply a miracle.  It's
not a configuration we expect to support.
