//    Compiler Options for Watcom C, C++ (os2)

-cwc

//    This file contains options to allow PC-lint to process source
//    files for your compiler.  It is used as follows:
//
//    lint  co-wcos2.lnt  source-file(s)
//

-d_M_IX86=300   // assume Intel 80386 architecture -- modify to suit
+rw(__declspec)
        // We now support __declspec directly so that the following
        // option is now commented out.  If trouble ensues you can
        // once again disable __declspec through this option.
        // -d__declspec()= // ignore this construct
-d_declspec=__declspec  // the single '_' version is occasionally used
-d__OS2__

  // additional reserve words needed

+rw(_Optlink,_Builtin)    // establish these as reserved words
+rw(_Seg16,_Far16,_System,_Pascal)   // also these are needed for os2 headers

+fcd            // makes cdecl significant -- used for proto generation
+fcu            // chars are by default unsigned
+fsu            // so are strings

	    // (no warnings, just syntax errors).  Comment out if you
	    // are actually linting library headers.  This
