ARGC/ARGV strangeness

[John Sellens]

| I thought I had understood argc/argv under GNU C, but I guess this 
| problem has me stumped.

One thing that's usually a very useful argument on the gcc command
line is -Wall.  (Put it in your Makefiles.)

On my system,
    % gcc -Wall a.c
    a.c: In function `main':
    a.c:9: warning: implicit declaration of function `strtol'
which would lead you to the strtol man page, and the need to
    #include <stdlib.h>
which would then tell you
    % gcc -Wall a.c
    a.c: In function `main':
    a.c:10: too few arguments to function `strtol'
which likely would have found the bulk of your problem.

Cheers

John
