This test has now been in for a few days. The test requires c++0x
support with a particular language defect fix implemented. So configure
checks for it and enables c++0x support if it works with gcc and in
those cases SAL_N_ELEMENTS is checked to make sure its not applied to
the wrong type of arguments, and as a side effect the STRING_CONST get
checked as well.

In practice this only happens for gcc 4.5.0 onwards, but that's the
version I have, so I'm relatively confident that any potential future
accidents will be caught.
