[cdt-dev] gcc extensions in index tests

[Nathan Ridge <zeratul976@xxxxxxxxxxx>]

When writing AST tests, we can specify that we want to enable
GNU extensions by passing useGnuExtensions=true to 
AST2TestBase.parseAndCheckBindings().

Is there a similar way to enable GCC extensions for an index
test, say in IndexCPPBindingResolutionTest? I am finding
that, by default, GNU extensions are disabled in these tests,
and I would like to write a test that involves code that
uses GNU extensions for bug 411196.

Thanks,
Nate
