The patch is already in gcc-trunk, gcc-5 and gcc-4.9 branch, so it will 
be part of 4.9.4.
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=68169

The only problem is that the current 4.11 toolchain is built with 4.9.3. 
Once gcc-4.9.4 is released and the RSB uses it, this part should work 
again. Until then it is necessary to manually change the RSB sources to 
a recent snapshot of the 4.9-branch for Ada.
