[Bug other/21629] New: [doc] gnat version requirements in install.texi

[joel at gcc dot gnu dot org]

The minimum requirements referenced in install.texi for GNAT seem to be out of
date.  Someone more Ada knowledgeable needs to confirm a minimum version for
4.0.0 and 4.1.0.  

For sure, to avoid problems building a cross GNAT, you should have a native GNAT
version that is the same as the version you are building cross.  It would be
nice to make this distinction here.

See http://gcc.gnu.org/bugzilla/show_bug.cgi?id=21247 for a report.

=========================================================================
In order to build GNAT, the Ada compiler, you need a working GNAT
compiler (GNAT version 3.14 or later, or GCC version 3.1 or later),
including GNAT tools such as @command{gnatmake} and @command{gnatlink},
since the Ada front end is written in Ada (with some
GNAT-specific extensions), and GNU make.

PR has been fixed some time ago already, documentation now says:

<<
In order to build a cross compiler, it is suggested to install
the new compiler as native first, and then use it to build the cross
compiler.
>>

------- Comment #1 from charlet at gcc dot gnu dot org  2005-11-17 15:23 -------
The minimum requirement is not out of date.

There has indeed always been a different requirement for cross compilers
where you need to first have a native compiler using the exact same
version, and that should indeed be mentioned in the doc, in addition to the
existing statement which seems correct to me.

Feel free to submit a patch to that effect.

Arno
