Sorry, I had missed that very sentence.

It's a bug in the (now discontinued) 3.2 branch, and it's fixed in 3.3 and
3.4 (CVS 20030503). If you run your template there, you will see that both
pointer to member functions and pointer to member variables evalutate to
*false*, which is the expected consistent behaviour.
