switch from c17 to gnu99

Browse Source 
I am choosing gnu99 over c99, since I am planning to use GNU extensions,
like bswap. (in a future commit)
Why I choose c99 over c17, is because this'll produce more portable
code.

c99 does not implement noreturn.h, thus I added it to the compiler
attributes header.
