There are, if I remember correctly, two versions of GCC, internal and
GPL.  The internal version is sold to commercial companies for money,
and Cygnus makes money.  The GPL version is the one we use.  I've never
worked on GCC, but it may be possible that you do have to agree to allow
Cygnus to use your changes and modifications.
