|

// * __STL_NO_BOOL: defined if the compiler doesn't have bool as a builtin

// type.
|
|
// * __STL_HAS_WCHAR_T: defined if the compier has wchar_t as a builtin type.
|
|
// * __STL_NO_DRAND48: defined if the compiler doesn't have the drand48
|

// function.
|
|
// * __STL_STATIC_TEMPLATE_MEMBER_BUG: defined if the compiler can't handle
|
|
// static members of template classes.
|
|
// * __STL_CLASS_PARTIAL_SPECIALIZATION: defined if the compiler supports
|
|
// partial specialization of template classes.
|
|
// * __STL_PARTIAL_SPECIALIZATION_SYNTAX: defined if the compiler
|
|
// supports partial specialization syntax for full specialization of
|
|
// class templates. (Even if it doesn't actually support partial
|
|
// specialization itself.)
|
|
// * __STL_FUNCTION_TMPL_PARTIAL_ORDER: defined if the compiler supports
|
|
// partial ordering of function templates. (a.k.a partial specialization
|
|
// of function templates.)
|
|
// * __STL_MEMBER_TEMPLATES: defined if the compiler supports template
|
|
// member functions of classes.
|
|
// * __STL_MEMBER_TEMPLATE_CLASSES: defined if the compiler supports
|
|
// nested classes that are member templates of other classes.
|
|
// * __STL_EXPLICIT_FUNCTION_TMPL_ARGS: defined if the compiler
|
|
// supports calling a function template by providing its template
|
|
// arguments explicitly.
|
|
// * __STL_LIMITED_DEFAULT_TEMPLATES: defined if the compiler is unable
|
|
// to handle default template parameters that depend on previous template
|
|
// parameters.
|
|
// * __STL_NON_TYPE_TMPL_PARAM_BUG: defined if the compiler has trouble with
|
|
// function template argument deduction for non-type template parameters.
|
|
// * __SGI_STL_NO_ARROW_OPERATOR: defined if the compiler is unable
|
|
// to support the -> operator for iterators.
|
|
// * __STL_USE_EXCEPTIONS: defined if the compiler (in the current compilation
|
|
// mode) supports exceptions.
|
|
// * __STL_USE_NAMESPACES: defined if the compiler has the necessary
|
|
// support for namespaces.
|
|
// * __STL_NO_EXCEPTION_HEADER: defined if the compiler does not have a
|
|
// standard-conforming header <exception>.
|
|
// * __STL_SGI_THREADS: defined if this is being compiled for an SGI IRIX
|
|
// system in multithreaded mode, using native SGI threads instead of
|
|
// pthreads.
|
|
// * __STL_WIN32THREADS: defined if this is being compiled on a WIN32
|
|
// compiler in multithreaded mode.
|
|
// * __STL_LONG_LONG if the compiler has long long and unsigned long long
|
|
// types. (They're not in the C++ standard, but they are expected to be
|
|
// included in the forthcoming C9X standard.)
|
|
|
|
|
|
// User-settable macros that control compilation:
|
|
// * __STL_USE_SGI_ALLOCATORS: if defined, then the STL will use older
|
|
// SGI-style allocators, instead of standard-conforming allocators,
|
|
// even if the compiler supports all of the language features needed
|
|
// for standard-conforming allocators.
|
|
// * __STL_NO_NAMESPACES: if defined, don't put the library in namespace
|
|
// std, even if the compiler supports namespaces.
|
|
// * __STL_ASSERTIONS: if defined, then enable runtime checking through the
|
|
// __stl_assert macro.
|
|
// * _PTHREADS: if defined, use Posix threads for multithreading support.
|
|
// * _NOTHREADS: if defined, don't use any multithreading support.

# define __USE_MALLOC
|
|
// BeOS used to trick the STL allocator (in stl_alloc.h) into falling back
|
|
// to malloc/free-allocation by setting MAX_BYTES to 0.
|
|
// By requesting to use those directly, we should get the same allocator,
|
|
// but will avoid the '... creates array of size 0'-warnings that are
|
|
// produced by 'gcc -strict' (for instance when building ICU).
|
|
// Alternatively, we could define _PTHREADS here and use the real STL
|
|
// allocator with posix threads enabled (however, this would have to be
|
|
// tested first, and most probably requires a rebuild of gcc2, too,
|
|
// in order to make sure that no code existing in libstdc++.r4.so is
|
|
// still using the old allocator).

// Other macros defined by this file:
|
|
|
|
// * bool, true, and false, if __STL_NO_BOOL is defined.

// * typename, as a null macro if it's not already a keyword.
|
|
// * explicit, as a null macro if it's not already a keyword.
|
|
// * namespace-related macros (__STD, __STL_BEGIN_NAMESPACE, etc.)
|
|
// * exception-related macros (__STL_TRY, __STL_UNWIND, etc.)
|
|
// * __stl_assert, either as a test or as a null macro, depending on
|
|
// whether or not __STL_ASSERTIONS is defined.
