Thanks for your bug report. Please note that gnupro is a Cygnus
product; this list is for help with the "official" GCC compiler. So
you really need to contact Cygnus for help.

Since I don't have gnupro, I use GCC 2.95.2. With that compiler, I
cannot see any difference in output. Since you did not report what the
correct output of the program should be, and what incorrect output you
got, it is hard to give help here.

That is a compiler bug. If it bothers you, you can add the flag
-Wno-unused.
