What do you mean with break?  Does this result in a compile, link, or run-time 
error?

I am able to build the sparc-rtems4.11-gcc with the latest GCC 4.8 branch 
without patches.  This WCHAR_TYPE_SIZE and WCHAR_TYPE patch seems be be 
unnecessary at least on SPARC.

The RTEMS testsuite results on SIS show nothing suspicious with this GCC.
