I was trying to generate a minimum ada runtime library for the avr (e.g. at90s8535) by copying the required *.ads and *.adb files to <prefix>/lib/gcc-lib/avr/3.4/ada-include and compile them.

What I got was a number of ICEs of the form:
+===========================GNAT BUG DETECTED==============================+
| 3.4 20030509 (experimental) (avr-unknown-none) Gigi abort, Code=305      |
| No source file position information available                            |
| Please submit a bug report; see            |
| Include the entire contents of this bug box in the report.               |
| Include the exact gcc or gnatmake command that you entered.              |
| Also include sources listed below in gnatchop format                     |
| (concatenated together with no headers between files).                   |

The files which generated errors were:
s-stalib.adb, s-parame.adb, i-c.adb,

I ran the compilation with 
avr-gcc -c -gnatg <filename>

flags -O and -mmcu=at90s8535 didn't make any difference

In file the reason for the ICE was the line:
pragma Import (Intrinsic, Asm);

In file the reason for the crash is the definition of type long:
type long  is range -(2 ** (System.Parameters.long_bits - 1))
     .. +(2 ** (System.Parameters.long_bits - 1)) - 1;
