Neat coincidence :) I was looking at it right now.

It's not that easy, the real problem turns out to be that the mingw tools
are extending the gcc-tools without setting/reflecting all the needed
*_DIRECTORY. Which causes it to get duplicate values for some of them and
when the GCC_ROOT_DIRECTORY is set the duplicates can be bogus.
I'm fixing it now by cleaning up the toolset. And like many programming
tasks fixing it makes for it having less code than before :-) Gota love how
things work out.
