True, but this kind of modification need not work on all platforms. Other platforms are happy with the MAX*LEN macros. But they are needed for the code to work properly on Hurd. And as far as I know the only C library for Hurd is glibc. All you need is a properly placed #ifdef __GNU__ in the code. Igor
