VMS Help CC, Messages, RESTRICTEXT2  *Conan The Librarian (sorry for the slow response - running on an old VAX)

 Message        The restrict type qualifier is a new feature in C99.
                Other C compilers might not successfully compile a
                program that uses this feature.

 Description    The use of the restrict type qualifier might not be
                portable to other C compilers.

 User Action    Be aware of this portability concern.
