The copyright file lists the components of GCC but doesn't mention GNAT there.  
From the copyright file:

	This is the Debian GNU/Linux prepackaged version of the GCC compiler
	collection, containing C, C++, Objective-C, Objective-C++, Fortran-95,
	Java, and Pascal compilers, and the libstdc++ support library.

In addition, the GNAT licensing issues are not so easy so I would be glad if 
these issues could be made clearer.

There are different editions of GNAT.  Currently, there are three different 
editions provided by Ada Core and there is GNAT as part of GCC.  One of the 
Ada Core GNATs is GNAT GPL Edition.  As far as I understand, this edition 
(which is released under the GPL) doesn't allow you to release your compiled 
code under a license other than the GPL.  Former GPL-licensed versions of 
GNAT by Ada Core (Technologies) had a special exception to allow the 
development of proprietary programs with GNAT (and probably also 
non-GPL-licensed free software).  The copyright file of the current gnat 
package (“gnat” without a dash and a version number) seems to contain this 
license.

I would like to know if the GCC GNAT can only be used to produce GPL-licensed 
binaries or if a special exception like the one in the classical free GNAT 
license applies to it.

In addition, (although this probably doesn't really belong to this bug report) 
I'd like to know if gnat-4.1 corresponds to recent releases of GNAT by Ada 
Core, especially if Ada 2005 is more or less supported.
