4Subject: [PATCH] Configure: fixed building libatomic test.
5
6Using "long *" instead of "AO_t *" leads either to -Wincompatible-pointer-types
7or -Wpointer-sign warnings, depending on whether long and size_t are compatible
8types (e.g., ILP32 versus LP64 data models).  Notably, -Wpointer-sign warnings
9are enabled by default in Clang only, and -Wincompatible-pointer-types is an
10error starting from GCC 14.
