Ada build help

Target Platform: Compaq Tru64 Unix 4.0F

A couple of questions:

(1)    What do I need in addition to gcc-3.1 (and the basics which it more
or less requires e.g. gmake, autoconf, automake, m4, etc) in order to get
the Ada portion of GCC-3.1 to build?  I can build all of GCC-3.1 with the
exception of Ada.  I understand that GNAT is written mostly in Ada and
requires Ada to build it or at least gnat1, gnatbind, etc.  The build
instructions are a bit confusing to me as they say I need a previous working
version of GNAT or GCC-3.1 or higher.  Since I am building GCC-3.1 and have
no Ada whatsoever, does this mean my only option is to build an earlier
verison of GNAT?  If this is the case will I encounter a similar problem
building an earlier version of GNAT?

I guess what I am really asking is how do I build GNAT without GNAT?

I am fairly new at this and these questions are probably pretty basic to you
guys but any help (or URL references on the subject) would be greatly
appreciated.




Thanks in Advance,
