Factor out the code to find gcc, and add a command-line option to override the default executable name. This should help cross-compilation by allowing a cross-gcc to be specified from the configuration file instead of only through the CC environment variable.

module scope4;
int main()
{
    int i;
    try
    {
        return i;
    }
    finally
    {
        //i = 1;
    }
}
