24    <para>Existing multilib distributions alter gcc to default to 32-bit
25    output.  Because our gcc defaults to 64-bit, we need to pass appropriate
26    options to both the compiler and the linker.  To prevent the build from
27    failing due to compiler warnings, the -Werror flag is removed.  The
28    Makefile already overrides any CC and ignores LDFLAGS in favour of
29    its own variables, so we need to use the following seds for a
30    successful compile and install.</para>
