questions about adding target to Binutils source

Sorry, but this is a requirement.  Your new code, if it is accepted, 
will be added to the current development sources at the head of the CVS 
repository, so we really need a set of patches that will apply to these 
sources.

The binutils already includes an extensive testsuite, but ideally when 
you contribute your code to support this new target you will also 
contribute some additions to the testsuite that check the features 
peculiar to your port.

Actually once you have contributed your port anyone will have the right 
to use that source.  They can develop new features for it, and if they 
wish they can submit them to us.  The port maintainer or a global 
maintainer will decide if they are suitable to be included into the 
sources in the FSF repository.  If they decide that the new feature(s) 
are not suitable they will explain why.  But, and here is the crucial 
bit, that person is free to maintain their own port, outside of the FSF, 
and continue to support and develop their own features.  This does not 
happen very often, but it does happen.

Right - but it is also important to mention that a submission cannot be 
accepted or reviewed until you have completed an FSF copyright 
assignment.  If you want I can email you the form to start the 
application for this assignment.
