So they still deserve fixing :)

I agree, but switching compilers is a great time to fix some warnings.  
It would take less then a day to fix the ones present today.

Sure, but that's not the only reason why an in-tree libgcc is a good  
idea.

Is your GCC 4.4 built on Windows or Linux? If Windows, perhaps it  
could become part of RosBE -- they have not been able to figure out  
how to build the compiler, hence my idea to use the MinGW binaries.
