There are a couple of other tests that appear to potentially have a
similar issue:
global-2_a.C
21:// { dg-final { scan-lang-dump-not {Reachable GMF '::printf[^\n']*' added}
module } }
global-3_a.C
15:// { dg-final { scan-lang-dump-not {Reachable GMF '::printf[^'\n]*' added}
module } }
Which I suppose maybe also should be updated in the same way; I guess
they don't fail on Solaris because they aren't actually correctly
testing what they think they are.
Otherwise LGTM.
