The package System.Img_Real is used to convert floats to string. You

% gcc-3.1 -gnatds testbug2.adb

fine on Sparc. I get the same result as the one you give as correct in
your mail.

The GNAT compiler based on GCC 2.8.1 is a top quality compiler. There
are some glitches in the GCC 3.1 port though.
