I'm still trying to understand how an option names -Werror=char-subscripts could trigger an error. There are no subscripts. AFAIK, the patched routines are not general purpose routines, so the char arguments can only take on values from the Fortran character set, which is a subset of the 7-bit ASCII set. Just commit the patch. I've wasted too much time trying to get an answer about how the option works. Nothing like cluttering working code.
