  Pragma:   optimize
 
  Syntax:   #pragma optimize( "[optimization switch list]", {off | on} )
 
  Summary:  Specifies optimizations to be performed. Must appear
            outside of a function.
 
  See also: Optimization Options
 
     The optimization switch list may be zero or more of the following:
     a, c, e, g, l, n, p, t, w. These are the same letters used with
     the /O compiler options. For example,
 
          #pragma optimize( "lge", off )
 
     Two special forms are supported. The form below turns off all
     optimization:
 
          #pragma optimize( "", off )
 
     The form below restores all optimization switch settings to their
     original (or default) settings:
 
          #pragma optimize( "", on )
