Linkage of GPLed GCC to Closed Source via XML or Perl

[Robert Dewar]

<<More seriously if someone creates a new GCC back-end to output something
that TODAY is not assembly language, then fine: the back-end is GPLed and
the resulting output can be used freely. In fact nothing proves that someday
one will not see a processor that you will directly program in XML, so that
XML would then be assembly language :-)

Please do not state dubious opinions as though they are legal fact. Remember
that what the GPL means can only ultimately be ascertained by litigation, and
many of the areas that people seem to think are black and white are quite
gray in practice.
