Yes, GNAT *is* a translator, in the sense that all compilers
are translators, it translates from Ada to machine language!
Actually we have dropped the designation Translator precisely
because it gets misunderstood (if you find this designation
somewhere, let us know, it is obsolete)

Since GNAT is written in Ada, of course you need an Ada
compiler to compile it. This must be achieved by finding
a binary for a previous 3.09 version, which may or may not
exist (Free BSD is not one of the targets for which ACT
provides a port). Alternatively you must build a cross-compiler
from some other target. The latter is indeed only a "little
snag", but only if you are familiar with GCC and know what
you are doing!

Doesn't FreeBSD run Linux executables? That is another
way to solve the problem, since Linux ports are definitely
available.
