	  They will be moved out to distinct directory in the next release, and default is going to be no own namespace 
	  with own iostreams.)
 	  For some compilers (VC6), this only works with _STLP_NO_OWN_NAMESPACE and _STLP_OWN_IOSTREAMS settings.

	* "prepare" target added to all makefiles in src/; should be run before using STLport;
	  on most platforms it's empty, on some of them it creates necessary symbolic links, etc.
	
	* stl/_deque.h : deque<>::erase bug (introduced in 4.1b4) fixed (thanks to BruceFlorman)

	  swap() changed not to invalidate any iterators, as prescribed by the standard

The following changes were made in 4.1 beta 4 since 4.1 beta 3 :
	
	* Simulation of class partial specialization (thanks to  Mat Marcus and Jesse Jones of Adobe)
	  used to provide following enhancements :
	
	 - type_traits are automatically specialized for all pointer types for all compilers, 
	   which makes them able to utilize type_traits-based optimizations when dealing with pointer types, 
	   automatically.
	
	 - all functions specialized for pointers and optimized via __type_traits
	   ( like copy()/copy_backward(), _uninitialized_xx) now enjoy this optimization for all compilers!
        
	- generic __value_type()/__difference_type()/__iterator_category() are written so user does not have
	   to supply any of its own even when partial specialization is not available.
	   (Note : gcc-2.7 and VC++ 5.x, 6.x have bugs which prevents them from using this enhancement, still)
	
	* <iterator> : by default, non-standard iterator query names like 
	  value_type()/difference_type()/iterator_category() are not used
	
	* <algo> : major revision:
	   - algorithms without explicit Compare() function expressed via the one that has it where possible.
	     This considerably reduces header size and reduces code bloat for programs which use both flavours of
	     those algorithms.
	   - some function bodies moved between  .c and .h 
	   - all functions used internally moved out to _algobase.h, so no other header includes <_algo.h> anymore
	   - find() specialized for random access iterators regardless of partial spec.

	* Dynamic libraries (.DLL and .so) : name versioning used to prevent clashes between STLport versions

	* src/ : code regrouped between .cpp files to provide for less executable size with dumb linkers;

	* locale subsystem initialization : startup changed to use statically allocated structures as much as possible;
	
	* <stl/_function.h> : basic stuff moved to _function_base.h ; 
	  other STL headers now include _function_base.h instead

	* _threads.h : MT support for OS/2 added (only tested with VAC++)

	* _stdio_file.h : added support for Solaris in ELF64 mode (thanks to Holger Stasch)

	  (Thanks to Thomas Witt et al.)

	* _ostream.h : fix for default unsigned char (thanks to  Holger Stasch)
	
	* all __STL_ABBREVS abbreviations moved aside in _abbrevs.h header.

	  please use __STL_USE_DEBUG_LIB and build debug STLport lib explicitly with "make debug_dynamic" 
	  if you really need it). "all" now builds 2 kinds : "release" and "STLdebug", for static and dynamic builds.

	* <fstream>, <fstream.h> : added initialization code for locale , same as in <locale> 
	  (thanks to George Trojan for the report)
