I've narrowed the breakage down to svn rev 141748 of
include/lldb/Symbol/ClangASTImporter.h
and these lines which I've ifdef'ed out in my local copy:
Index: include/lldb/Symbol/ClangASTImporter.h

I'm assuming you folks are building with the clang-based FE shipped with XCode
4.* yes? I haven't determined for a fact that clang (or its associated header
files) is at fault here, but given the choice between believing clang (+lib) or
gcc 4.5.1, I'd tend to bet on gcc (and I'll happily eat those words if I'm
wrong!). Just what standard library are you folks using anyway?
Sorry I haven't had time to track this down any further...
