A signed integer type of maximal width that exceeds the C99 specifications.
Typically this might be of width 128 where the whole tool chain, in particular the preprocessor, only supports 64.
This typedef is always defined. In the bestcase, it coincides with intmax_t - this can be checked for with a macro of the same name.
