clang compile error on mingw / gcc 3.4.5

Hi all,

I am trying to get llvm / clang to build on mingw with support for objc.
Building llvm (svn trunk) went quite smoothly, however building clang gave
me the following error:

I traced this back in svn to revisions 73917 and 73921, where this was changed.
It seems as if gcc 3.4.5 isn't able to deal with the used template construct.

Best regards,

Hi Ronald,

I'll take a look at this today.

Hi Ronald,

I just committed a potential fix:

Please let me know whether or not it resolves the problem for you.

Your fix seems to work, since now I am able to compile. Thanks.
The resulting binary does nothing but crash, though, sadly.
