Message        HP C RTL prefix table version mismatch:  RTL table is
                V<major>.<minor>, compiler needs V<major>.<minor>.

 Description    In most cases, the HP C compiler will automatically
                map names of C standard library functions to their
                corresponding names in the HP C RTL shareable image.
                In many cases, this is done simpl by adding a "DECC$"
                prefix to the name.  In order for this mapping to
                work, the compiler accesses an RTL mapping table.
                The compiler also requires that the version of the
                RTL mapping table be compatible with the version of
                the compiler.  In cases where the versions are
                incompatible, this message is generated.  In these
                cases, no name mapping will be performed.  The most
                common cause of this message is specifying an old RTL
                name in the /PREFIX=RTL="name" compiler qualifier.

 User Action    Specify a new RTL on the /PREFIX=RTL qualifier.  If
                no qualifier was used, it might be necessary to
                reinstall the compiler and/or RTL.  For more
                information, consult the HP C Run-time Library Manual
                for OpenVMS Systems.
