Yep.  That was indeed the culprit thanks.

I moved the msvcrt specfic objects to libmsvcrt-moldname.a for example.  I had
failed to modify the specs file to use it that way.

I.E.:
mkdir /usr/lib/crtdll
  mv <crtdll specific files> /usr/lib/crtdll
mkdir /usr/lib/msvcrt
  mv <msvcrt specific files> /usr/lib/msvcrt

I would then do:

gcc ... -B /usr/lib/crtdll

OR

gcc ... -B /usr/lib/msvcrt


QUESTION:
  Would it work to put the gcc-lib/... directory under crtdll & msvcrt for the
specific objects?  If not how would you setup to be able to choose one over the
other?


Thanks for your efforts,
Earnie
