Message        The target macro "<name>" does not match the
               compiler's target.  This will likely cause incorrect
               code paths to be taken.

Description    On OpenVMS I64, some users have tried defining the
               macro __ALPHA explicitly using /DEFINE or a #define
               in a /FIRST_INCLUDE file as a quick way to deal with
               source code conditionals that assume that if __ALPHA
               is not defined then the target must be a VAX.
               Defining __ALPHA will cause many of the CRTL and
               other OpenVMS headers to take the wrong path for I64.

User Action    Remove any definitions of Alpha target macros, and if
               necessary correct the preprocessor conditionals that
               seemed to require an Alpha target macro to get the
               desired effect.  E.g.  change "#ifdef __ALPHA" to
               "#ifndef __VAX" or "#if defined(__ALPHA) ||
               defined(__ia64)".
