Then tried with OSF1 foo V5.1 2650 alpha and gcc version 3.4.1

which won’t even compile.

Finally tried with Linux foo 2.6.20-1.2948.fc6 #1 SMP i686 i386 GNU/Linux and gcc version 4.1.2

and it runs… …except when you press ctrl-D (or pass /dev/null as an input):

Segmentation fault

Other than that, gccalc is a nice piece of sw.
