/WARNINGS

  The /WARNINGS qualifier lets you specify  whether  the  compiler  displays
  informational, warning, or alignment messages.

  The format of the /WARNINGS qualifier is as follows:

     /[NO]WARNINGS[=({[NO]WARNINGS      },...)]
                     {[NO]INFORMATIONALS}
                     {[NO]ALIGNMENT     }
                     {ALL               }
                     {NONE              }

  Specifying /WARNINGS=NOWARNINGS causes the compiler  to  suppress  warning
  messages.   Specifying  /WARNINGS=NOINFORMATIONALS  causes the compiler to
  suppress informational messages.  Specifying /WARNINGS=NOALIGNMENT  causes
  the  compiler  to suppress alignment warning messages.  Alignment warnings
  are suppressed by default; to get alignment  warning  messages,  you  must
  explicitly specify /WARNINGS=ALIGNMENT on the command line.

  The  /NOWARNINGS  qualifier  causes   the   compiler   to   suppress   any
  informational, warning, or alignment messages.

  /WARNINGS = ALL is the same  as  /WARNINGS  =  (INFORMATIONALS,  WARNINGS,
  ALIGNMENT).  /WARNINGS = NONE is the same as /NOWARNINGS.

  The default is /WARNINGS = (INFORMATIONALS, WARNINGS, NOALIGNMENT).
