Okay, stupid question time:

If I run this program:

main(){
    printf("Goodbye cruel world\n");
    exit(-1);
    }

funny things happen.  Under amigados, the program runs once, and then the
disk spins again and gives a random AmigaDOS error.  Under the CShell,
the program executes twice!  Also, if the return value is -2 or -3, 
the AmigaDOS CLI doesn't give any error (and runs once) but cshell still
executes it twice.  And for any negative value, the cshell variable
_lasterr is always 20.

What's up?

The CLI is Amigados 1.3, and the cshell is "Shell V4.02A" by Dillon,
Drew, Borreo & Dieni.
