//  this file defines  wrapper classes to hide non-conforming 
// std::char_traits<>  and std::allocator<> traits
//  and Includes : config_macros.hpp (defines config macros
//  and compiler-specific switches)

// Non-conformant Std-libs fail to supply conformant traits (std::char_traits,
//  std::allocator) and/or  the std::string doesnt support them.
// We don't want to have hundreds of #ifdef workarounds, so we define 
// replacement traits.
// But both char_traits and allocator traits are visible in the interface, 
// (inside the final string type),  thus we need to keep both 
// the replacement type (typedefed to 'compatible_type') for real use,
// and the original stdlib type (typedef to 'type_for_string') for interface
//  visibility. This is what Compat* classes do (as well as be transparent 
// when good allocator and char traits are present)
