// -09/23/98 <klr> Ported -m option to generate make dependencies

// -F46082.51<daz> Transferred -m, -mmin, mall, -mdepend options to com.sun.tools.corba.se.idl.toJava

// since these are IBM-specific (see f46838); cleaned-out dead code.

// -D57482   <klr> Added method setDefaultEmitter so could be overridden.
