That's not quite right however, as the input on one side is often just a char * on one side. Instead just use char *, the first field in config_generic. This fixes a -Warray-bounds warning with some versions of gcc. While the warning is only known to be triggered for <= 15, the issue the warning points out seems real, so apply the fix everywhere.
