Added define 'unused_' for '__attribute__((unused))'. The oldest version of GCC with online docs (GCC 2.95.3, released in March 16, 2001 [1]) already has support for this attribute, so it doesn't make sense to check the version. Renamed 'noreturn' to 'noreturn_' for consistency. [1] https://gcc.gnu.org/onlinedocs/ Signed-off-by: Antonio Niño Díaz <antonio_nd@outlook.com>
