Patience :-)

All patches must be sent to the gcc-patches list as well as the
libstdc++ one.

The 'test' variable is not useless, in some cases the VERIFY macro
expands to an expression using 'test', so it shouldn't be removed.
See testsuite/util/testsuite_hooks.h

The other changes look OK, although I'm curious where those unused
pieces came from (probably copied from another file). I wonder if it
would be better to check the count, rather than just stop using it.
