Subject: [PATCH] Silence sys/sdt.h comparison of unsigned expression < 0 is always false.

Some arm g++ setups would complain about the wchar_t "signedness detection":
sys/sdt.h:102: error: comparison of unsigned expression < 0 is always false

jistone said: "((T)(-1) < 1)" would still get the right boolean value,
and shouldn't trigger range errors like "unsigned is never < 0".
