 Message        The inline and __inline keywords will be interpreted
                with GCC style semantics.  To get C99 semantics,
                please specify -accept nogccinline.

 Description    The C99 standard has a slightly different
                interpretation of the keyword inline than in GCC.
                The GCC __inline keyword also differs from the COMPAQ
                C __inline keyword.

 User Action    Use the command line specifier -accept nogccinline.
