As far as I know, such hosts are non-existent. While what you say is quite correct for other pointer types, the C Standard requires char * and void * to have the same representation and alignment and notes that that is intended to allow them to be used interchangably as arguments to unprototyped functions, so only a deliberately perverse implementation would fail. -Larry Jones In my opinion, we don't devote nearly enough scientific research to finding a cure for jerks. -- Calvin _______________________________________________ bug-gnulib mailing list bug-gnulib@gnu.org http://lists.gnu.org/mailman/listinfo/bug-gnulib
