Use the Definitions/Directives Options dialog box to define options for any
 subsequent build.

 The default values of the options will be reflected when the dialog box comes
 up.

 If there are Definitions/Directives Options settings defined for the current
 context, they will be reflected when the dialog box come up, and they will
 take precedence over the default settings.

 If qualifiers have been specified when invoking MMS, the Definitions/Directives
 Options settings will reflect the qualifier values, and they will take
 precedence over the context settings.
