 *
 * To hold user-definable portion of STLport settings which may be overridden
 * on per-project basis.
 * Please note that if you use STLport iostreams (compiled library) then you have
 * to use consistent settings when you compile STLport library and your project.
 * Those settings are defined in host.h and have to be the same for a given
 * STLport installation.

/*
 * Use this switch for embedded systems where no iostreams are available
 * at all. STLport own iostreams will also get disabled automatically then.
 * You can either use STLport iostreams, or no iostreams.
 * If you want iostreams, you have to compile library in ../build/lib
 * and supply resulting library at link time.
 */
/*
#define _STLP_NO_IOSTREAMS 1
*/

/*
 * Set _STLP_DEBUG to turn the "Debug Mode" on.
 * That gets you checked iterators/ranges in the manner
 * of "Safe STL". Very useful for debugging. Thread-safe.
 * Please do not forget to link proper STLport library flavor
 * (e.g libstlportstlg.so or libstlportstlg.a) when you set this flag
 * in STLport iostreams mode, namespace customization guaranty that you
 * link to the right library.
 */
/*
#define _STLP_DEBUG 1

/*
 * You can also choose the debug level:
 * STLport debug level: Default value
 *                      Check only what the STLport implementation consider as invalid.
 *                      It also change the iterator invalidation schema.
 * Standard debug level: Check for all operations the standard consider as "undefined behavior"
 *                       even if STlport implement it correctly. It also invalidates iterators
 *                       more often.

/*
 * _STLP_NO_CUSTOM_IO : define this if you do not instantiate basic_xxx iostream
 * classes with custom types (which is most likely the case). Custom means types
 * other than char, wchar_t, char_traits<> and allocator<> like
 * basic_ostream<my_char_type, my_traits<my_char_type> > or
 * basic_string<char, char_traits<char>, my_allocator >
 * When this option is on, most non-inline template functions definitions for iostreams
 * are not seen by the client which saves a lot of compile time for most compilers,
 * also object and executable size for some.
 * Default is off, just not to break compilation for those who do use those types.
 * That also guarantees that you still use optimized standard i/o when you compile
 * your program without optimization. Option does not affect STLport library build; you
 * may use the same binary library with and without this option, on per-project basis.

 * to simulate hiding them into rel_ops. This was proved to resolve many compiler bugs with ambiguity.

 * If STLport use its own namespace, see _STLP_NO_OWN_NAMESPACE in host.h, it will try

 * please define the following switch and then use stlport::
 */
/*

/*
 * _STLP_WHOLE_NATIVE_STD : only meaningful if STLport uses its own namespace.
 * Normally, STLport only imports necessary components from native std:: namespace.
 * You might want everything from std:: being available in std:: namespace when you
 * include corresponding STLport header (like STLport <map> provides std::map as well, etc.),
 * if you are going to use both stlport:: and std:: components in your code.
 * Otherwise this option is not recommended as it increases the size of your object files
 * and slows down compilation.
 * Beware, if you do not use STLport iostream (_STLP_NO_IOSTREAMS above), ask STLport to
 * not rename std:: in stlport:: and try to have access to whole native Standard stuff then
 * STLport will only throw exceptions from the std namespace and not from stlport.
 * For instance a problem in stlport::vector::at will throw a std::out_of_range exception
 * and not a stlport::out_of_range.
 * Notice that STLport exceptions inherits from std::exception.

 * The agregation of strings using the + operator is an expensive operation
 * as it requires construction of temporary objects that need memory allocation
 * and deallocation. The problem can be even more important if you are adding
 * several strings together in a single expression. To avoid this problem STLport
 * implement expression template. With this technique addition of 2 strings is not
 * a string anymore but a temporary object having a reference to each of the
 * original strings involved in the expression. This object carry information
 * directly to the destination string to set its size correctly and only make
 * a single call to the allocator. This technique also works for the addition of
 * N elements where elements are basic_string, C string or a single character.
 * The drawback can be longer compilation time and bigger executable size.
 * Another problem is that some compilers (gcc) fail to use string proxy object
 * if do with class derived from string (see unit tests for details).
 * STLport rebuild: Yes

 * (of 16 chars when writing this doc) to avoid systematically memory allocation

 * prefer systematical dynamic allocation turn on this macro.

/*
 * To reduce the famous code bloat trouble due to the use of templates STLport grant
 * a specialization of some containers for pointer types. So all instanciations
 * of those containers with a pointer type will use the same implementation based on
 * a container of void*. This feature has shown very good result on object files size
 * but after link phase and optimization you will only experiment benefit if you use
 * many container with pointer types.
 * There are however a number of limitation to use this option:
 *   - with compilers not supporting partial template specialization feature, you won't
 *     be able to access some nested container types like iterator as long as the
 *     definition of the type used to instanciate the container will be incomplete
 *     (see IncompleteClass definition in test/unit/vector_test.cpp).
 *   - you won't be able to use complex Standard allocator implementations which are
 *     allocators having pointer nested type not being a real C pointer.

/*
 * To achieve many different optimizations within the template implementations STLport
 * uses some type traits technique. With this macro you can ask STLport to use the famous
 * boost type traits rather than the internal one. The advantages are more compiler
 * integration and a better support. If you only define this macro once the STLport has been
 * built you just have to add the boost install path within your include path. If you want
 * to use this feature at STLport built time you will have to define the
 * STLP_BUILD_BOOST_PATH enrironment variable with the value of the boost library path.
