My animal mamba doesn't like this one bit.

I suspect the reason is that it's big-endian (PPC) and the endianness
hacking in the test is simply wrong:

        syswrite($file,
                 pack("L", $ENDIANNESS eq 'little' ? 0x00010019 : 0x19000100))
            or BAIL_OUT("syswrite failed: $!");

pack's L code should already be performing an endianness swap, so why
are we doing another one in the argument?

            regards, tom lane
