[PATCH] misc cleanup

[Marek Polacek]

This patch fixes some miscellaneous stuff in the testsuite.
See https://gcc.gnu.org/ml/gcc-patches/2014-09/msg02656.html for more info.

Tested on x86_64-linux: vanilla results == results with this patch ==
results with this patch and gnu11 as a default.

Applying to trunk.
