Good! I'll push it later. Thanks for testing! :-)

Ah! But, according to:
  http://gcc.gnu.org/install/configure.html

--with-specs is not a valid, recognised option. So in this case, I'm not sure
how ./configure treats it. It seems it tries to assign the right-hand part
(after the '=' ) to the variable whose name in on the left-hand part (before
the '=' ).

What are you trying to do by passing specs at _build_ time?
