Building with GCC 14 fails at the configure step with:
./configure: error: libatomic_ops library was not found.
The error is not caused by a missing library, but by an unrelated
"incompatible pointer type" error in the test program:
...
checking for atomic_ops library
objs/autotest.c: In function 'main':
objs/autotest.c:9:48: error: passing argument 1 of 'AO_compare_and_swap' from incompatible pointer type [-Wincompatible-pointer-types]
This used to be a warning, but it is an error since GCC 14.[1]
Fix this by patching the test program in order to use the correct
pointer types.
