...ta type, but we do not. C23 states that bool has 1 value bit and some padding bits (?6.2.6.2) so it can be stored in char-sized storage (i.e. bytes) or multiples thereof. And that _Bool is a alternative name for bool. f) is complier-dependent: for interoperability with C or R, code should use c_bool from iso_c_binding (Fortran 2003). Fortran compilers store LOGICAL in compiler-dependent ways, and for a long time we got away with assuming that was equivalent to int (so LOGICAL values could be passed to and from with int* on the C/R side). But sometime around GCC 8 they changed to int_leas...
