His original intent with GNU was to replace Unix wi= th a more free version by rewriting everything.

(You might also bring up an intere= sting point that GIGI in GNAT was written by Stallman or some other =E2=80= =9CC guy=E2=80=9D instead of the NYU or AdaCore team, which also might have= led to the borrowing of a preexisting GIGI layer.) The *tree* packages in GNAT are autogenerated from a *def file, these map o= nto the C equivalent in the GCC backend so that GNAT can build the trees pr= operly.
