C++ ptrmemfun break if FUNCTION_BOUNDARY < 2 *BITS_PER_UNIT

[Mark Mitchell]

I think this all makes sense.

I should have thought of this issue when implementing the new ABI;
somehow, it didn't occur to me.

I would sugest that if you're going to use an enum to represent
different choices about representation here (which seems reasonable)
that you have the TARGET_ macro evaluate to an enum, rather than a
boolean.  That would be simpler.  Have it default to
ptrmemfunc_vbit_in_pfn in defaults.h, and then you can eliminate the
conditional compilation in decl.c.

Thank you for taking on the task of fixing the problem.
