I'd like to add, that AFAIS nothing forbids you to do development with
gnat-2006 (using the full ASIS support for debugging and perhaps
generating source code and then compile the project with gccada and
ship these binaries closed source style to the customer.

And its actually not necessary: The Toolchain might be under GPL as it
likes (it's OK in my book that nobody can create a closed source tool
from the compiler), but what is annoying is if the GPL infects any
tool compiled _with_ the compiler. This is less freedom not more.
