It's been a couple weeks since I sent this out, so here's a quick
ping.  Details reproduced below:

Section 5.10 of the C++ standard states:

"In addition, pointers to members can be compared, or a pointer to
member and a null pointer constant.  Pointer to member conversions
(4.11) and qualification conversions (4.4) are performed to bring them
to a common type."

The C++ front end fails to perform the indicated conversions when
comparing pointers to member functions.  This patch rectifies this.

Tested with a C/C++/Java bootstrap and testsuite on i686-pc-linux-gnu.
