testsuite failures on v7 branch due to concept-checks

[Jonathan Wakely]

Chris, Paolo,

I'm seeing the following FAILs on the v7 branch when concept-checks are
enabled:

FAIL: 25_algorithms/count/check_type.cc (test for excess errors)

Sorry I didn't catch those earlier, I always test with concept-checks
but haven't tested the v7 branch for a while.  Add -D_GLIBCXX_CONCEPT_CHECKS
to scripts/testsuite_flags to reproduce this.

I doubt I'll have time to analyze what's happening this week, sorry.
