Yes, this patch slipped under my radar.  It would be good if you - Rainer -
would have pinged on it.  As far as I recalled I awaited at that time a full
patch by Rong on this subject. (See comment #16 and after that).

Nevertheless patch looks ok.  I will give it some testing and will apply it
after that.  The change to undef mkdir in libgcc's part of the patch looks to
me being the real patch.  The patch in gcc's part is more cosmetic part getting
rid of this (also mentioned to Rong too) wrong _WIN32 check.
