Yes, the patch was from the time the companion libs where build shared.
We where trying to build our tool-chains with the gcc 4.4.3 at that time which
failed due to several errors, of which this fixed one. Because of
these error we kept using gcc 4.3.4,

I pulled the current crosstool tree yesterday and did some tests with
our configurations and gcc 4.4.3.
I was able to build a working tool-chain, so I believe the patch is no
longer needed when building the companion libs
statically, however I still needed to patch the build of cloog which
failed to link against libstdc++.

I attached a patch which fixed the problem (for me)
