How to provide alternatives in sequence

Suppose I have the following class: ``` struct Foo{ virtual void before(); virtual void do(); virtual void after(); }; ``` With the sequence approach I can make sure, those functions...

`--abbreviate-paths` leads to build config clashes

### Brief problem description I was using something like `boost.locale.std boost.locale.icu` together with `--abbreviate-paths` and noticed failures as - `./b2 --abbreviate-paths boost.locale.std=off` - `./b2 --abbreviate-paths boost.locale.icu=off` created the same folders...

Outdated defect macros for Haiku

A user did a portfile (build definition of some sort) for Haiku and noticed that although GCC 13 is being used Boost.Config unconditionally defines C++11 defect macros: https://github.com/boostorg/config/blob/boost-1.83.0/include/boost/config/platform/haiku.hpp#L19-L22 As [reported](https://github.com/boostorg/locale/issues/191#issuecomment-1694695004)...

Enable UTF char types (char16_t, char8_t etc.) when available

4

Currently there are defines like `BOOST_LOCALE_ENABLE_CHAR16_T` to enable `char16_t` and similar for others. I find that a bit... difficult. We have `BOOST_NO_CHAR16_T` and similar to detect the availability automatically. So...
