 Message        The /NAMES=LOWERCASE qualifier will be removed in a
                future version of the compiler.  Use /NAMES=AS_IS if
                your application must generate global names in
                lowercase.

 Description    While the C language has always required identifiers
                with internal linkage to be treated case
                sensitively,it traditionally permitted
                implementations to monocase identifiers with external
                linkage.  Modern standards require C/C++
                implementations to preserve the case of identifiers
                with external linkage.  As VMS and other operating
                systems that traditionally implemented monocasing
                chose uppercase as the convention, /NAMES=LOWERCASE
                runs contrary both to the C and C++ standards and to
                traditional conventions.  Continued support for this
                option interferes with support for compatibility
                between old code compiled with /NAMES=UPPERCASE and
                new code compiled with /NAMES=AS_IS.

 User Action    Use /NAMES=AS_IS, making source code changes as
                needed.
