Of course I do, I was just asking for what the actual overhead is.

No, this target (and others) do support weak, just not weakrefs. The
macros should reflect their meaning (SUPPORTS_WEAKREF) and have all
necessary knowledge in one place (acinclude.m4) instead of playing games
with both SUPPORTS_WEAK and GTHREAD_USE_WEAK.
