[comp.bugs.4bsd] pcc bug

wendt@arizona.edu (Alan Lee Wendt) (06/24/87)

Bug:  pcc compiles without complaint the program:

main(x,y)
    int x, main;
    {
    printf("oops\n");
    }

Another one of many PCC front end problems.  A fix, of sorts - it
causes the compiler at least to recognize that "main" is not given in
the argument list.
