It means that a symbol was used but it was never declared.

For instance, in this program:

  --------------------
  #include <stdio.h>
  int main()
       {
       printf("The value is %d\n", x);
       return 0;
       }
  --------------------

The symbol 'x' is not declared.  Variables have declarations.  Functions
have prototypes or function bodies.  All of those things are definitions.
When a symbol is used that is not an inherent part of the language then it
must be defined.

In the program below 'x' is no longer undefined.

  --------------------
  #include <stdio.h>
  int main()
       {
       int x = 3;

       printf("The value is %d\n", x);
       return 0;
       }
  --------------------
