Silence GCC's Wunused-function firing in compilation tests

Browse Source 
The whole GCC kinda sucks around warnings, this is yet another place
where pragmas manipulating warnings don't work properly and thus a
warning has to be disabled globally... luckily, this time it is
happening in selftest file and thus it isn't too problematic to just
turn that warning of for the entire file.
