[c06e893]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
[a5f7c53e]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>
