This is a difference between F2008 and its revision. WG5 decided last 
year to adopt this proposal (see N1975):

Number: UK-06
Title: Remove restriction on ERROR STOP
Status: For Consideration
Basic Functionality:
Remove restriction on error-stop
Rationale:
There is no standard way to issue a diagnostic message from a PURE
procedure.  A program should be able to execute an error termination
with a meaningful message.

Specification:
Remove the restriction on the appearance of an ERROR STOP statement
in a PURE procedure.

Syntax:
Delete 'or <<error-stop-stmt>>" in C1287 [313:8].

Cheers,

John.
