Lost the C++ standard recognition while upgrading from 2.1-RC1 to 2.2

Hello guys,

I'm using QtCreator as a simple code editor for a C++ project (not related to Qt) which is cross-compiled to sh4.

When using the 2.1-RC1 version of QtCreator, I had access to the standard C++ classes and headers with no problem whatsoever: syntax highlighting was working well and I got auto-completion for vectors and maps and strings, etc.
When I switched to 2.2, I lost all that. I see that QtCreator 2.2 still recognizes the standard C include files, but the C++ headers are not taken in account.
Note that the parser still analyses my code, and I can navigate into my classes with no problem.

I don't use the QtCreator building system because of the cross-compiling, I simply use the console.
This means that if QtCreator uses the compiler output to figure out the include paths, that's possibly the problem.

This bug report is a suggestion following this discussion: http://developer.qt.nokia.com/forums/viewthread/5804/
