That's a bit confusing. The main sources of the compiler are distributed
under the GPL period (not a modified GPL).

Components of ASIS and the runtime are distributed under a significantly
modified GPL (see text of modification below) that make it possible to

a) create tools using the ASIS interface not covered by the GPL
b) compile programs using the GNAT runtime not covered by the GPL

respectively
