Fix undefined behaviour.
* lib/bitrotate.h (rotl16, rotr16, rotl8, rotr8): Case x to
'unsigned int', to avoid shift operations on 'int'.
* lib/xmemdup0.c (xmemdup0): Don't invoke memcpy with a zero size.
* tests/test-count-leading-zeros.c (main): Use a random number that has
as many bits as TYPE, not only 2*15 or 2*31 bits.
* tests/test-count-trailing-zeros.c (main): Likewise.
* tests/test-count-one-bits.c (main): Likewise.
* tests/test-memmem.c: Don't include "null-ptr.h".
(main): Use zerosize_ptr() instead of null_ptr().
* modules/memmem-tests (Files): Remove tests/null-ptr.h.

@node func @section func The @code{func} module makes sure that you can use the predefined identifier @code{__func__} as defined by C99 in your code. A small example is: @smallexample #include <config.h> #include <stdio.h> /* for printf */ int main (void) @{ printf ("%s: hello world\n", __func__); @} @end smallexample Note that @code{sizeof} cannot be applied to @code{__func__}: On SunPRO C compiler, @code{sizeof __func__} evaluates to 0.
