This patch does manage to complete a build, but tests (both standalone and
libgomp) using alias fail with "unresolved symbol".  This is because it cal=
ls
write_fn_proto which generates a linker marker for the alias, which makes t=
he
linker think there's such a function, and when it cannot find it, it genera=
tes
an "unresolved symbol" error.=
