/* USER-SELECTABLE CONFIGURATION MACROS */
/* */
/* This file contains the default configuration macro definitions for */
/* a standard build of the FreeType library. There are three ways to */
/* use this file to build project-specific versions of the library: */
/* */
/* - You can modify this file by hand, but this is not recommended in */
/* cases where you would like to build several versions of the */
/* library from a single source directory. */
/* */
/* - You can put a copy of this file in your build directory, more */
/* precisely in `$BUILD/freetype/config/ftoption.h', where `$BUILD' */
/* is the name of a directory that is included _before_ the FreeType */
/* include path during compilation. */
/* */
/* The default FreeType Makefiles and Jamfiles use the build */
/* directory `builds/<system>' by default, but you can easily change */
/* that for your own projects. */
/* */
/* - Copy the file <ft2build.h> to `$BUILD/ft2build.h' and modify it */
/* slightly to pre-define the macro FT_CONFIG_OPTIONS_H used to */
/* locate this file during the build. For example, */
/* */
/* #define FT_CONFIG_OPTIONS_H <myftoptions.h> */
/* #include <freetype/config/ftheader.h> */
/* */
/* will use `$BUILD/myftoptions.h' instead of this file for macro */
/* definitions. */
/* */
/* Note also that you can similarly pre-define the macro */
/* FT_CONFIG_MODULES_H used to locate the file listing of the modules */
/* that are statically linked to the library at compile time. By */
/* default, this file is <freetype/config/ftmodule.h>. */
/* */
/* We highly recommend using the third method whenever possible. */

/* some problems when compiling the library in strict ANSI mode. */
/* */
/* For this reason, the use of 64-bit integers is normally disabled when */
/* the __STDC__ macro is defined. You can however disable this by */
/* defining the macro FT_CONFIG_OPTION_FORCE_INT64 here. */
/* */
/* For most compilers, this will only create compilation warnings when */
/* building the library. */

/* ObNote: The compiler-specific 64-bit integers are detected in the */

/* ZLib library selection */
/* */
/* This macro is only used when FT_CONFIG_OPTION_USE_ZLIB is defined. */
/* It allows FreeType's `ftgzip' component to link to the system's */
/* installation of the ZLib library. This is useful on systems like */
/* Unix or VMS where it generally is already available. */
/* */
/* If you let it undefined, the component will use its own copy */
/* of the zlib sources instead. These have been modified to be */
/* included directly within the component and *not* export external */
/* function names. This allows you to link any program with FreeType */
/* _and_ ZLib without linking conflicts. */

/* DLL export compilation */
/* */
/* When compiling FreeType as a DLL, some systems/compilers need a */
/* special keyword in front OR after the return type of function */
/* declarations. */
/* */
/* Two macros are used within the FreeType source code to define */
/* exported library functions: FT_EXPORT and FT_EXPORT_DEF. */
/* */
/* FT_EXPORT( return_type ) */
/* */
/* is used in a function declaration, as in */
/* */
/* FT_EXPORT( FT_Error ) */
/* FT_Init_FreeType( FT_Library* alibrary ); */
/* */
/* */
/* FT_EXPORT_DEF( return_type ) */
/* */
/* is used in a function definition, as in */
/* */
/* FT_EXPORT_DEF( FT_Error ) */
/* FT_Init_FreeType( FT_Library* alibrary ) */
/* { */
/* ... some code ... */
/* return FT_Err_Ok; */
/* } */
/* */
/* You can provide your own implementation of FT_EXPORT and */
/* FT_EXPORT_DEF here if you want. If you leave them undefined, they */
/* will be later automatically defined as `extern return_type' to */
/* allow normal compilation. */
/* */
/* Do not #undef these macros here since the build system might define */
/* them for certain configurations only. */

/* #define FT_EXPORT(x) extern x */
/* #define FT_EXPORT_DEF(x) x */

/* Glyph Postscript Names handling */
/* */
/* By default, FreeType 2 is compiled with the `PSNames' module. This */
/* module is in charge of converting a glyph name string into a */
/* Unicode value, or return a Macintosh standard glyph name for the */
/* use with the TrueType `post' table. */
/* */
/* Undefine this macro if you do not want `PSNames' compiled in your */
/* build of FreeType. This has the following effects: */
/* */
/* - The TrueType driver will provide its own set of glyph names, */
/* if you build it to support postscript names in the TrueType */
