Off the top of my head, the conditions are:

- use the GCC from the FSF that the libgnat is part of; i.e. you
  cannot (without a lot of work) use the GNAT GPL 2005 Edition with
  libgnat from the FSF.  You can choose either GCC 3.4.4 (more stable)
  or GCC 4.0.2 (more features).  Avoid GCC 3.3.6 (Ada is buggy).

- distribute the sources to libgnat, or point people to these sources,
  with your program.  If you modify libgnat, you must publish the
  modified sources of libgnat.

- you can choose the license for your program, you don't have to
  distribute the sources of your program.

All of them, except GCC 3.4.4 on powerpc.
