> The GMGPL license in either GNAT Pro runtime or GNAT-FSF runtime permits software that is licensed under a license that is incompatible with the GPL to be linked with the output of Ada standard generic libraries that are supplied with GNAT without breaching the license agreement.
If you use the version of GNAT provided as part of GCC from GNU (which is a year or so behind), or the paid-for version of GNAT from AdaCore, you can distribute your program without distributing the source. If, however, you use the GPLed version of GNAT from AdaCore, your own code has to be distributed under something compatible with the GPL.
The Wikipedia article could do with a cleanup, really.
