I did another build on Windows 11 ; this time using gcc-11.2 (via MSys2
MinGW), c++20
I did 2 runs one on command line and one on x64 Native Tool MSCV 2022
Also used address-model=64 to avoid Python 32-bit
No errors but compiled way less files this time ; typically it was around
~8000+
this time "...updated 3693 targets.."
command line i used ;
b2 cxxstd=20  address-model=64 toolset=gcc --build-type=complete stage

as usual got warning for auto_ptr and this one ;

C:/msys64/mingw64/include/c++/11.2.0/ext/new_allocator.h:145:26: warning:
'void operator delete(void*, std::size_t)' called on unallocated object
'boost::wave::util::SimpleStringStorage<char, std::allocator<char>
>::emptyString_' [-Wfree-nonheap-object]
  145 |         ::operator delete(__p
      |         ~~~~~~~~~~~~~~~~~^~~~
  146 | #if __cpp_sized_deallocation
      | ~~~~~~~~~~~~~~~~~~~~~~~~~~~~

  148 | #endif
      | ~~~~~~
  149 |                          );

If needed I can put the whole build outputs  on gist.

Only one question is it normal to use  address-model=64 or should this be
detected thru b2 or CMake and if it causes any other needed
libraries skipped because there was quite a bit of difference in the
updated amount
