//    Compiler Options for Borland C, C++ 3.10 and earlier

//    This file contains options to allow PC-lint to process source
//    files for your compiler.  It is used as follows:
//
//    lint  co-bc.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(87)   // windef.h contains a botched #ifdef
-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(726)  // inhibits error involving extraneous comma in enumerations
            // within library header graphics.h
-elib(553)  // use of undefined preprocessor variables like #if __STDC__
            // within string.h
-elib(123)  // stdarg.h defines __size() and stdio.h uses __size parameter
-elib(579)  // Borland C++ compensates for sub int params in stdarg.h
            // this is still a dangerous nonportable practice for user programs
-elib(743)  // '\x80' is used in limits.h
-elib(773)             // offsetof() macro causes some problems

-emacro(507,FP_OFF)  // inhibit loss of information message.
--emacro(507,offsetof)  // inhibit loss of info message in macro
-emacro(413,offsetof)  // use of NULL pointer creates a stir
-emacro(545,offsetof)  // addressing an array member is OK
-emacro(792,assert)  // inhibit void cast of void message
-emacro((???),va_arg)   // the va_arg() macro can yield 415, 416, 661, 662
			// 796 and 797 (out-of-bounds errors).

+rw(_export,_import)    // needed especially for Windows programming
-sld10          // sizeof(long double) is 10.
-elib(770)  // WORDREGS, BYTEREGS, REGS, SREGS  defined in both
            // bios.h and dos.h
-etd(origin) // this will inhibit complaints about 'origin' type differences
            // this occurs when both bios.h and dos.h contribute the
            // identical struct's to a program.
-e793       // inhibit 'ANSI limit reached' --
            // limits are impractically low with Borland headers
-function(exit,_exit)   // _exit() is like exit()
-function(exit,__assertfail)  // __assertfail() is like exit()
-emacro(570,disable,_disable,enable,_enable)  // allow (char) 0xFA
-emacro(734,putc)   // don't complain about items being too large.
-emacro(732,putc)      // inhibit loss of sign
-d_asm=asm          // Borland accepts both "_asm" and "asm"
-d__asm=asm         // and __asm

//  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.

-esym(534,*printf,*putc,*scanf)  // often called without checking return
-esym(534,close,creat,fclose,fflush)

-esym(534,puts,strcat,strcpy)

//  These are the wide char variants of printf-scanf family

-wprintf( 1, wprintf )
-wprintf( 2, fwprintf, swprintf )
-wscanf( 1, wscanf )
-wscanf( 2, fwscanf, swscanf )

// 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
-elib(1720) //assignment op has non-const parameter
-elib(655)  // bitwise operator combining compatible enum's
-elib(641)  // converting enum's to int
-elib(537)  // repeated include file (ios.h)
-elib(1511) // member (rdbuf) hides nonvirtual member
-elib(1712) // default constructor not defined for class
-elib(1736) // redundant access specifier
-esym(1702,operator<<,operator>>)  // both a member and an ordinary function

// These functions return things that are frequently ignored.

-esym(534,ostream::operator<<,istream::operator>>)

// 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(783)      // line in config.h does not end in new-line
-elib(522)      // doesn't use the return value of underflow();
-elib(1066)  // same name declared as "C" and not "C"
-elib(1724) //argument to copy construct should be const ref
-elib(1722) //assignment operator does not return ref
-efile(766,mem.h)  //included by iostream.h but not really used
-elib(1704)   // constructor with private access declaration
-elib(1708,1709)   // minor C/C++ declaration conflict
-elib(1735)   // default parameter within virtual function
