With a very small and obvious Makefile patch, I got a working:
GNU Ada version 3.1 20011008 (experimental) (i686-pc-linux-gnu)
        compiled by GNU C version 3.1 20011008 (experimental).
and start looking on assembler outputs.

I'm very pleased compared with GNAT 3.13p: Much better inlining, more
efficient stack handling, some new error messages� and definitly shorter
code (especially on bound checking). I'm still checking if the code is
correct. But even -fssa seems to work fine. The vast improvement (to me) are
the enumeration converters 'Val, 'Image. The necessary tables look very much
like my old C64 BASIC ROM.

1  Following Errors are new to me:

 - pragma Inline in package specification do not longer work for code in
   package bodies, but can not reproduce this in a very short example.

 - Instantiation of a generic with a derivated type now cleanly rejects
   nonderivated integral types.
