//    This file contains options to allow PC-lint to process source
//    files for your compiler.  It is used as follows:
//
//    lint  co-msc40.lnt  source-file(s)
//
-d_M_IX86=300   // assume Intel 80386 architecture -- modify to suit

        // 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
            // 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(19)   // useless declarations (lone semicolons)
-elib(123)  // function-like macro name used as non macro
-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
-elib(514)  // allow #if <boolean> | <boolean>
-elib(553)  // undefined preprocessor variables assumed 0
-elib(726)  // extraneous comma in enum definition

//  SREGS, WORDREGS, BYTEREGS are defined in both bios.h and dos.h
//  and accordingly you MAY get type differences based on 'origin'.
//  If so, use the following options:
//      -etd(origin)
//      -elib(770)

-format=%(%f(%l)\s:\s%)%t\s%n:\s%m
        // error format similar to MSC
        // Note that %c can also be used to specify column
-e46    // allows bit-fields to be other than int or unsigned
+fan    // allow anonymous unions
+fdi    // Use directory of the including file
-fbo    // disable the bool type
-fdh    // do not append a .h to header names
-ffb    // do not establish a separate scope for declares within for clauses
-esym(123,min,max)  // allows users to use min, max as variables

		 // for MSC 4.2 make it 1020

-d_inline=__inline  // _inline is the same as __inline
-sld10          // sizeof(long double) is 10.
-function(exit,_exit)   // _exit() is like exit()
-function(exit,_assert)   // _assert() is like exit()
-emacro(506,assert) // don't warn about constant value Boolean
-emacro(734,putc)   // don't complain about items being too large.
-emacro(415,_FP_SEG)  // access of out-of-bounds pointer
-emacro(740,FP_SEG,FP_OFF)  // unusual casts
-emacro((???),va_arg)   // the va_arg() macro can yield 415, 416, 661, 662
			// 796 and 797 (out-of-bounds errors).
-emacro(413,offsetof)  // use of NULL pointer creates a stir
-emacro(545,offsetof)  // addressing an array member is OK
-e793           // inhibit 'ANSI limit reached' --
		// limits are impractically low with MSVC headers
-esym(628,eof)  // failure to provide argument information for eof()
-esym(773,L_tmpnam)     // defined with an unparenthesized '+'

//  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.

-elib(522) //function return value ignored

// The following additional options seem to be needed.

-elib(506) // constant value Boolean
-elib(620) // el or one? (some constants end in 'l' not 'L')
-elib(648) // overflow in computing constant (3<<16)

-elib(1504) // apparently useless structs
-elib(1708,1709) // minor C/C++ declaration conflict
-elib(1707) // operator new declared w/o 'static'
-elib(1722) // assignment op does not return reference
-elib(149)  // default argument found in C code.
-elib(578)  // declaration of time hides delaration of global time().
-elib(761)  // two equivalent typedef declarations
-elib(1065)  // same name declared as "C" and not "C"
-elib(1066)  // same name declared as "C" and not "C"

-elib(1516) // data member hides inherited member
-elib(1509) // base class destructor is not virtual
-elib(1735) // default parameter within virtual function

// Special Notice:  You may be receiving mysterious 1058 errors
//   when you use "iomanipulator"s.  For example:
//   cout << setw(4) << 4;
//   results in Error 1058 (assigning a const to a ref) because the
//   manipulator setw returns a non-lvalue which is assigned to a reference.
//   This reflects an oversight in the Microsoft header file: iomanip.h
//   Therein you may change the declaration:
//     friend ostream& operator<<(iostream& s, IOMANIP(T) & sm) { ...
//   to:
//     friend ostream& operator<<(iostream& s, const IOMANIP(T) & sm) { ...
//   to reflect the fact that sm is not modified by this function.

+fll            // enable long long
-d__STDC__=0    // Starting with 2.0, the tests within Microsoft header

-dWIN32         // this is necessary because without WIN32 being defined
