Subject: Add explicit void pointer cast for Perl user data

This fixes a compilation error on GCC 14.

Quoting https://gcc.gnu.org/gcc-14/porting_to.html

  GCC no longer allows implicitly casting all pointer types to all
  other pointer types. This behavior is now restricted to the void *
  type and its qualified variations.

  To fix compilation errors resulting from that, you can add the
  appropriate casts, and maybe consider using void * in more places
  (particularly for old programs that predate the introduction of void *
  into the C language).
