I guess you mean "The Ada compiler that comes with > GCC 3.3". What does "gnatmake -v" say about the version? Um, yes, I was under the impression that ACT wouldn't release more gnat versions but instead go through gcc. gnatmake -v says: GNATMAKE 3.3 20030329 (prerelease) Copyright 1995-2002 Free Software Foundation, Inc. > > What is new since 3.15? > > Bugs.
