Hi, everyone

    I have tired to compile boost from boost_1_81_0 to boost_1_88_0 with MSYS2 by getting source code from https://www.boost.org/releases/latest/

    And I got two kinds of result:
    (1) That is fine to be compiled from boost_1_81_0 to boost_1_84_0;
    (2) but there is some problem from boost_1_84_0 to boost_1_88_0 like following 

**# ./b2 -j4 toolset=gcc address-model=64 link=static,shared threading=multi --build-type=complete

Please consult the documentation at 'https://www.bfgroup.xyz/b2/'.**

Before that, I already run: ./bootstrap.sh --with-toolset=gcc --with-libraries=all --prefix= successfully.

So, the question is why the compilation problem happen and how to fix it ?

Thanks a lot !
