Sorry, but you missed my point: the currently committed gcc/ada/ChangeLog
file contains the wrong entry I quoted in my previous email.

Here it is again, verbatim:

<<
2010-06-12  Kai Tietz

	PR ada/43731
	* gcc-interface/Makefile.in: Add rules for multilib x86/x64
	mingw targets.
>>

So since we seem to be in agreement about the intent, please fix the above
entry on trunk, and then OK to merge.
