Main is called with 3 arguments. This is *not* an undocumented feature.
I quote from the manual page for exec(2):
------------

     When a C program is executed, it is called as follows:

          main(argc, argv, envp)
          int argc;
          char **argv, **envp;

------------
BTW, I do know of a U**X that doesn't support this. I maintain a slightly
hacked version of PWB/UNIX.  This UNIX version doesn't have environment
variables.
