           Summary: Documentation: missing (Optional) keyword for
                    parameters of get_command_argument() and
                    get_environment_variable()
           Product: gcc
           Version: 4.6.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: libfortran
        AssignedTo: unassig...@gcc.gnu.org
        ReportedBy: thenl...@users.sourceforge.net


The argument VALUE of the get_command_argument() intrinsic is correctly marked
as optional in the Syntax section, but in the Arguments section the (Optional)
keyword is missing.

Style issue: For the LENGTH and STATUS arguments the keyword is written as
(Option), not (Optional).

The arguments VALUE,LENGTH,STATUS,TRIM_NAME of the get_environment_variable()
intrinsic are correctly marked as optional in the Syntax section, but in the
Arguments section the (Optional) keyword is missing.
