//    Compiler Options for Linux and GCC

//    This file contains options to allow FlexeLint to process source
//    files for the Gnu compiler (GCC) for versions earlier than
//    2.95.3.  It is used as follows:
//
//    lint  co-gnu.lnt  source-file(s)
//
//    If you are using GCC on some other system you will need to change
//    the following options:

+cpp(.cc,.C)  // extensions for C++ that are commonly used in addition
            // to the default extensions of .cpp and .cxx
+fld        // support gcc's label designators

-cgnu       // defines LANGUAGE_C for C modules
// +fus     // activate this option if your compiler supports an assumed
            // using namespace std at the beginning of processing
-d__i386__  // a define of this type is machine-dependent
            // modify if you are running on non-intel hardware.
-d__linux__ // Linux define!
//-d__mc68000__  //a machine dependent define

-di386=1          // needed for some Unix's
-a#machine(i386)  //  #assert's machine(i386)  (SVR4 facility).

// To let FlexeLint know where to find header files you need one
// or more -i options where each -i option is followed immediately
// by a single directory.
// For example:     -i/usr/include
// Use 'cpp -v emptyfile.cpp' to get a list of C++ search directories.
// Use 'cpp -v emptyfile.c' to get a list of C search directories.

// You may use the following option to include standard C headers.
// This would come before other -i options.

-i/FlexeLint/supp/ansi  // This we humbly offer as a collection of ...
            // ANSI (i.e ISO) header files.  Replace the word "FlexeLint"
            // with the name of the directory in which FlexeLint has
            // been installed.  Note, you might want to replace "ansi"
            // with "posix".

-si4    // int's are typically 4 bytes
-sp4    // ptr's are typically 4 bytes           

//    end of system dependent options.

-fdc       // do not Distinguish plain Char as a unique type.
           // i.e. char is either signed char or unsigned char
           
            // while processing library headers
-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(15)   // redeclaration of symbol
-elib(516)  // lots of redeclarations in Linux stdlib.h
-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(553)  // undefined preprocessor variables are taken as 0
-elib(410)  // unusual size_t
-elib(767)  // differently defined macro
-elib(624)  // typedef symbol redeclared
-elib(607)  // parameter substitution within string

-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

//  The following options were found necessary when processing
//  the Unix headers within /usr/include

+fdi            // Use the directory of the including file

+ppw(ident)     // Tolerate #ident
+rw(__inline)   // enable the (non-standard) __inline keyword
+rw(__inline__)   // enable the (non-standard) __inline__ keyword

//  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.
