This is the symptoms of a bug in WINDOZE, which is that it don't free
DPMI selectors as it should. Worth to note is that the bug still
unfixed. 

The fix is to just restart the make (in another bash window, as you
did) and it will continue where it stopped.


Sorry I can't comment on the rest as I haven't tried compiling gcc (in
a while).
