C++ FAIL counts and the effect of demangler fix

[Andrew Cagney]

Michael,

Can you elaborate?  The numbers look really intersting however, to me
(someone that has avoided C++ since cfront 1.2) they are meaningless. 
Why is there the divergence, for instance - where is it comming from.

BTW, we don't have to get back to anything.  As far as I know, the
failures are being caused by an unlreased version of GCC that has
changed its mangler ABI in some incompatible way.  It would be nice if
the problems were resolved, however, they are _NOT_ a 5.1 release
criteria so not especially high on my radar.  5.1 needs to work with
real compilers installed on real machines.

	enjoy,
