[PATCH] fix build on uClibc

Use cue_unused / cue_dead2 for the unused/non-returning annotation macros,
as uClibc defines a struct member called __unused in stdio.h when built
with locale support, breaking the build.

According to ANSI C 4.1.2.1, defines beginning with '__' are reserved
for the implementation, so shouldn't be used in user code.
