If it's an FSF GCC including Ada then it will be the version that
allows you to build proprietary code. That would include GNAT from
Cygwin or as part of your Linux distribution.

If it's a non-PRO ('GPL') GNAT from AdaCore, the extra permission
isn't available.

You can look at the source of the RTL; if it's the GPL version, there
will be a region about 30 lines into the header comment where the
extra permissions have been removed.

Probably rather easier to say 'gnatls -v'. If the output starts with
something like GNATLS GPL 2007 (20070402-41) then you have a GPL
version.

If it's more like GNATLS 4.0.0 or perhaps GNATLS PRO x.y.z (don't have
one here), it's got the GMGPL permissions.
