* lib/autoconf/c.m4 (_AC_C_C23_TEST_GLOBALS):
In use_u8, add parens to pacify GCC 15 -Wbool-compare,
and use sizeof to make it a conforming integer constant expression.
Do not test stdbit.h, as some current sort-of-C23 environments
lack it and want to use options like -std=gnu23 on such platforms.
Use null_pointer to pacify GCC -Wunused-const-variable.
