calls bug + fix

[Tom Gerardy]

The version of calls we have has a bug for static functions which are used
before being defined, i.e.:

static void initialize();
  ...
main (argc, argv)
{
  initialize();	/* calls dies here */
  ...
}
  ...
static void initialize()
{
  ...
}

Follows a patch to fix this problem.
