So I will need gnat to be able to get gnat... Could anyone please
recomend a good ftp-site where I can find a binary version which works
with Slackware 3.1?

Installing from source means patching gcc, does this mean that I will
have to replace gcc with a new one for gnat to work?

Get gnat-3.10p binaries for linux.  Install that.  You then have all
you need to rebuild gnat-3.10p sources with gcc-2.7.2.

Yes.  The 2.7.2 patches add some setjmp/longjmp enhancements to gcc
in order for gnat to work properly.

Alternately, you can build gnat-3.10p with egcs-1.0.3a and not have to
apply any patches whatsoever (which might be a good idea, since the
gcc-2.7.2 patches included with gnat-3.10p break the gcc optimizer
when compiling glibc-2.0.6).

If I get a working binary version, is there be any reason to recompile
it from source?

Are these patches included in the binary version of gnat or will I have
to install them manually? If so, where will I get them?

Thanks for your reply!

Depends on whether you are ok or not with losing g++ or g77 support in
the gcc executable.

They are source patches and, of course, the gnat binaries were compiled
with them (wouldn't work without them).

There is no need to recompile GNAT on any Linux version. The binary
version on <ftp://cs.nyu.edu/pub/gnat/> work on any Linux distribution,
however some tweeking is necessary on newer distributions such as
Red Hat 5.0 and other that have already switched to glibc2. See
<http://www.gnat.com/chat/2781.html> for the small things that
have to be done on glibc2 systems (creating symbolic links for
crtbegin.o etc as well as changing one runtime library signal
data structure).

The only binary versions I saw there just now are for I386 and I486.

Nothing for Alpha, Sun. etc.

Am I misunderstanding the NYU naming convention, or should the quoted
statement be qualified as only applying to Intel ?

No there are indeed binaries for Alpha (OSF 3.2 and 4.0) and Sun,
Solaris and
Irix there.  Depending on your ftp client, it may be easier to pick out
the
binaries with a command like "ls *.bin.tar.gz," which shows me only the
binaries.

Linux is available on Alpha, SPARC ant other platforms, but GNAT is
not available off-the-shelf for Linux on those other platforms.

There may be some extra hoops to go through if you want C++ as well, I
don't think ACT include cc1plus & the matching includes/libs
.. certainly not in Linux 3.10p.

Also, the source for Rolf Ebert / Markus Heritsch ada-mode makes many 
references to XEmacs. Is this code common?

Isn't that just font-lock?  My version of emacs (20.2.1) does color
syntax hightlighting already.
