[Stlport-announce] STLport 5.1.0 RC1

[<du...@us...>]

First candidate for STLport 5.1.0 has been released. Feel free to check 
support for your platform/compiler and report your feeling in mailing list.

Great thanks to major contributors for this release:
Ulrich Eckhardt
Michael Fink
Eric Sanford

and also to all posters that help making this library so great.

Here is the list of major improvements coming with this version.

- Major modifications

   * Folder architecture: All configuration files are now in 
stlport/stl/config folder.
   stlport/stl_user_config.h renamed and moved as 
stlport/stl/config/user_config.h.
   stlport/stl/_site_config.h renamed and moved as 
stlport/stl/config/hosts.h.
   STLport configuration now also try to seperate platform configuration 
from compiler
   one.

   * Allocators implementation is in src folder to enhance 
encapsulation. Default
   allocator when using STLport without building it (_STLP_NO_IOSTREAMS) 
is the simple
   new/delete based allocator, node allocator is the default when 
building the lib.

   * Expression template for string concatenation is activated per 
default. Go to
   user_config.h file to disable it.

   * Access to native headers has been modified to make STLport less 
dependant on
   native headers internal includes, should improve portability.

   * Segregation of headers has been improved. You might have to add now 
missing
   functional or algorithm Standard headers include in your code.

- Enhancements

   * Support enhancements:
     - Borland compilers starting with the free one (5.5.1)
     - Visual Studio 2005 for Windows CE
     - Digital Mars compiler (experimental)
     - Use of intrinsic type traits support of Visual Studio 2005

   * Improved meta programming techniques especially in uninitialized_* 
algorithms.
   If you need a vector of null pointer prefer to write 'vector<void*> 
v(10)' rather
   than 'vector<void*> v(10, (void*)0)'.

   * Fully functional pointer specialization feature 
(_STLP_USE_PTR_SPECIALIZATIONS).

   * Extension of template search methods in associative and hashed 
container has
   been completed.

   * STL safe mode: Now detect badly implemented strict weak ordering 
functors, assert
   if a < b && b < a. Same for equivalent functor used in hash container 
implementation,
   assert if a <=> b but !(b <=> a).

   * Improved locale creation delay on Windows platform.

   * STL containers implementation now correctly handle allocators with 
state. This kind
   of allocator has to overload swap method if any specific action has 
to be made when
   swaping 2 instances.

   * STLport is ready for safe string functions *_s 
(_STLP_USE_SAFE_STRING_FUNCTIONS)

   * Many bug fixes, see etc/ChangeLog.
