We should only allow
a) elemental functions
b) we currently check gfc_init_expr_extensions():
  /* FIXME: This should be moved into the intrinsic definitions.  */
  static const char * const init_expr_extensions[] = {
    "digits", "epsilon", "huge", "kind", "maxexponent", "minexponent",
    "precision", "present", "radix", "range", "selected_real_kind",
    "tiny", NULL
  };
I'm neither sure whether this is correct nor whether this is complete.

See: "7.1.7 Initialization expression" in Fortran 2003 and
"7.1.6.1 Constant expression" in Fortran 95.

There is at least the following difference between the standards:
F2003: [Allowed is] "A reference to an elemental standard intrinsic function,
where each argument is an initialization expression"

F95:
"An initialization expression is a constant expression in which the
exponentiation operation is
permitted only with an integer power, and each primary is
[...]
(4) An elemental intrinsic function reference of type integer or character
where each argument is an initialization expression of type integer or
character"
