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

["joel at gcc dot gnu dot org" <gcc-bugzilla 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The minimum requirements referenced in install.texi for GNAT seem to be out of
date.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.
