//    co-gnu3.lnt
//    Compiler Options for GCC versions 2.95.3 and later

//    This file contains options to allow FlexeLint to process source
//    files for the Gnu compiler (GCC).
//
//    flint  co-gnu3.lnt  source-file(s)
//
//    If you are using GCC on some other system you will need to change
//    the following options:

-cgnu       // Notifies FlexeLint that gcc is being used.
// +fus     // activate this option if your compiler supports an assumed
            // using namespace std at the beginning of processing

// Begin: System Dependent Options
// -------------------------------

-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 normally come before other -i options.

-i/FlexeLint/supp/ansi  // This is offered 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: System Dependent Options

            // to the default extensions of .cpp and .cxx

            // 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.
