I'd use scm_func_cast<scm_t_blabla> (actual_func) in order to mimic what reinterpret_cast does, but the implementation looks awfully heavy-handed and GCC-8 specific.
Any chance that an implementation via a double cast (with something like void * in between) will work? Strictly speaking that's worse than casting from one function pointer to another since function and data pointers need not be the same size on segmented architectures, but lots of code does stuff like that anyway. Or we just disable that specific warning completely: casting from one function pointer to another is "I mean it" territory. It's part of the Guile API and we cannot really expect people to circumvent it every time. https://codereview.appspot.com/357770043/ _______________________________________________ lilypond-devel mailing list lilypond-devel@gnu.org https://lists.gnu.org/mailman/listinfo/lilypond-devel
