//    Compiler Options for Metaware High C

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

            // while processing compiler (library) header files ...
-wlib(1)    // sets the warning level within library headers to 1
	    // (no warnings, just syntax errors).  Comment out if you
	    // are actually linting library headers.  This
	    // option makes obsolete options of the form -elib(axxx) where
	    // xxx >= 400 which may be retained for historical reasons.
-elib(652)  // suppress message about #define of earlier declared symbols
-elib(762)  // suppress message about multiple identical declarations and
-elib(760)  // suppress message about multiple identical macro defs
-d_stdio_defs_included=0   // used in header files
-d__1167=0                 // used in header files
-d__HIGHC__=1              // used in header files
+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
--emacro(506,_MAXSTRING)   // constant value Boolean
-emacro(413,offsetof)  // use of NULL pointer creates a stir
-emacro(545,offsetof)  // addressing an array member is OK
-emacro(415,FP_SEG)  // access of out-of-bounds pointer
+rw(_to_semi)       // enable _to_semi -- ignores information
                    //   up to and including a semi-colon.
-d_pragma=_to_semi  // make _pragma equal to _to_semi.
-dpragma=_to_semi   // make pragma equal to _to_semi.
-d_packed=          // ignore _packed
+rw(_Far,_Near,_Pascal,_Fortran)   // Additional reserved words
-d_CC()=        // ignore these constructs
-elib(553)      // undefined preprocessor variables assumed 0
-elib(726)      // extraneous comma within enum
-elib(778)      // constant expression evaluates to 0
-elib(43)       // vacuous type for variable
-elib(140)      // allow early modifiers in library headers.
+ppw(c_include) // activate #c_include
-d_MSDOS        // pre-defined variable
-d_I386         // pre-defined variable
-esym(745,_profile_start)
-function(exit,_exit)   // _exit() is like exit()
-d_near=   -d_far=        // can't yet handle _far char *,
                          // we need char _far *
-d_char_t=unsigned        // For High C, this is built-in

-si4
-sp4

-emacro(734,putc)   // don't complain about items being too large.
-emacro((???),va_arg)   // the va_arg() macro can yield 415, 416, 661, 662
                        // 796 and 797 (out-of-bounds errors).

//  The following functions exhibit variable return modes.
//  That is, they may equally-usefully be called for a value
//  as called just for their effects.  Accordingly we inhibit
//  Warning 534 for these functions.
//  Feel free to add to or subtract from this list.

// The following options are required by most compilers to
// noiselessly process iostream.h

-elib(1717) //empty prototypes
-elib(522) //function return value ignored
-elib(1053) //prototypes cannot be distinguished
-elib(1721) //unusual operator =() declaration

// The following additional options seem to be needed.

-fdc       // do not Distinguish plain Char as a unique type.
           // i.e. char is either signed char or unsigned char
-elib(747) //significant prototype coercion
-elib(740) //unusual pointer casts
-elib(1029) //default argument repeated -- can't dist. char, signed char
-elib(1055) //call to rdbuf() questioned?
-elib(1708,1709) // minor C/C++ declaration conflict
