Thanks, applied.

I'm not even sure if ccache is used when compiling on the build farm...

The test suite is disabled for non-GCC builds since some of the tests
require GCC. If the test suite had been run on the Tru64 and AIX hosts,
the bug would have been found too, so I think what should be done (and
which I have planned but haven't done yet) is to fix so that the test
suite can be run for all compilers without false failures. It should be
a matter of doing compiler feature detection in the framework and then
making it possible to skip some tests depending on the feature detection
result. (Volunteers are welcome!)
