i wonder how that works with gcc then.  or does it not ?

unfortunately, iirc, you have to sign papers for each GNU project.  so having 
signed papers for the GCC project won't help with newlib.  you'll have to 
contact the FSF at assign@gnu.org to get papers in place.  i don't recall if 
libgloss/newlib are sep projects, but i'd mention them both to be sure.

(note: i'm not related to the FSF at all ... i'm just relaying my 
understanding of how things work)
