I've forgotten to reword this after changing the logic.  New message:

commit dcd7bed33cc274e8f3565ad02fb1fbc04bc845fb

    libstdc++: Add a test for <version> FTM redefinitions
    
    This test detects redefinitions by compiling stdc++.h and <version>,
    by disabling the system_header pragma on the latter, to allow
    warnings in it.  Thanks Patrick Palka for the suggestion.
    
    libstdc++-v3/ChangeLog:
    
            * testsuite/17_intro/versionconflict.cc: New test.
