But since you are building gcc (gcc4x), it is already GPL'd software.
The GNAT GPL license wouldn't affect gcc4x, because gcc itself is
already under the GPL. What gcc4x produces in terms of executables
and libraries is not tainted by gnat/gpl; it is tainted only by
whatever license applies to gcc4x and its libraries.
