Compiling GNAT GPL 2006 into GCC 4.1.1

["deadlyhead" <s.brutzman@gmail.com>]

This is my first attempt at actually compiling GNAT, so I'm coming here
for any insight into the process.

I'm currently using a non-Ada GCC 4.1.1 and would really like to get
GNAT up and running so I can start developing in my favorite language
again.  (My GNU/Linux box is based on Linux From Scratch, and it's only
been recently that I've been able to acquire the GNAT sources to set up
a _real_ compiler.)  Like any good technophile, I would really like to
use the latest GNAT sources from AdaCore as I'm eager to utilize the
new features from the Ada 2005/2006 standard.  Herein lies the
problem...

AdaCore only provides information on building their release sources
into the 3.4.6 series GCC release, with absolutely no information on
the 4.x series of compilers.  The sane route is likely to say,
``Alright, I'll just go ahead and use GCC 3.4.6 for GNAT and 4.1.1
otherwise,'' but I really can't stand the thought of having two GCC
builds around like that, where I could instead have a beautifully
integrated environment.  On top of that, I hate the thought of being
forced to use obsolete technology, either an old GCC or Ada95 when an
Ada 2005/2006 compiler is available.

Now, normally I'd just go for it, replacing files in the GCC tree with
the AdaCore files where necessary (ada directory, etc), however there
are specific .dif files and such provided for the 3.4 GCC which most
assuredly do not work with GCC 4.1.1.  As I imagine this could create
serious problems, I'm hesitant to just give it a go.

I'd like to know if anyone on this list has attempted integrating GNAT
GPL 2006 into their GCC 4.1.1 builds, and if so, were they successful?
Is there any information regarding the matter available on the web?
(Extensive searching of this news group as well as much Googling have
proven somewhat fruitless.)  Does anybody know of any attempts by the
GCC team to integrate GNAT 2006 sources into GCC in the near future
(possibly series 4.2)?

I'll be posting to the GCC lists tomorrow with queries, and likely will
simply give GNAT 2006/GCC 4.1.1 a shot if nobody has any information on
the matter.  Thanks to anybody willing to offer up whatever knowledge
they possess.
