[PATCH] Quash warning

[Roland McGrath]

> This quashes one unused-but-set warning.  Ok?

This is OK, but if there are many that come from the same macros then it
might be worth looking into a different approach that makes the macro
itself arrange to suppress the warning, rather than cluttering up a lot of
source code.  I'm not sure if just adding a 'foo = foo;' statement is
enough, but it might be.


Thanks,
