As Pascal says, it's FSF GCC 4.9.0, and the FSF's change notes are the
reference for the compiler.

GNAT GPL 2014 (for Mac) supports C, C++, Ada, and Objective C. My
release additionally supports Fortran and Objective C++. In all cases,
the compiler itself is built without change. I had to rebuild the
command 'gnat', because the original build with the compiler failed with
SIGSEGV; something to do with exceptions, I need to report this but I'm
a bit too vague on the details.

The only functional change to the tools was to gprbuild; it still
(wrongly) passes -c to ranlib, and I've improved the handling of static
stand-alone libraries (like [1]; I didn't patch gnatmake in the
compiler, because gprbuild is the proper tool for building libraries on
Mac OS X).

The RTS copyright is GPL 3 with the runtime exception; the tools are GPL
(I expect GPL 3, haven't checked). The ones where this could cause a
problem are ASIS, GNATColl, and XMLAda; AUnit, GDB and GPRbuild are
build/test tools.

README and patches are at the same place as the compiler tarball.
