Using "long *" instead of "AO_t *" leads either to -Wincompatible-pointer-types or -Wpointer-sign warnings, depending on whether long and size_t are compatible types (e.g., ILP32 versus LP64 data models). Notably, -Wpointer-sign warnings are enabled by default in Clang only, and -Wincompatible-pointer-types is an error starting from GCC 14. Signed-off-by: Edgar Bonet <bonet@grenoble.cnrs.fr>
