Yes.
It's hard to argue with a terse compiler or maintainer. Perhaps i
should have picked an easier target like
http://gcc.gnu.org/onlinedocs/gcc/Atomic-Builtins.html: "GCC will
allow any integral scalar or pointer type that is 1, 2, 4 or 8 bytes
in length" of which that TItype from the testsuite testcase is not.

In any case thanks for the clarification.
