    # 1) I have no idea why, but GCC 10.2 fails to build Boost.Filesystem with
    #    the following errors:
    #
    #        libs\filesystem\src\path.cpp:36:11: fatal error: windows_file_codecvt.hpp: No such file or directory
    #           36 | # include "windows_file_codecvt.hpp"
    #              |           ^~~~~~~~~~~~~~~~~~~~~~~~~~
    #        compilation terminated.
    #        libs\filesystem\src\windows_file_codecvt.cpp:25:10: fatal error: windows_file_codecvt.hpp: No such file or directory
    #           25 | #include "windows_file_codecvt.hpp"
    #              |          ^~~~~~~~~~~~~~~~~~~~~~~~~~
    #        compilation terminated.
    #
    #    This seems to be a compiler bug, since the file is _definitely_ there,
    #    and Clang 8.0.1 builds it successfully.  This only applies to Boost
    #    versions up to and including 1.60.0 for some reason.  I can easily
    #    reproduce this locally.  TODO: remove when GCC on Cygwin is treated
    #    with a bugfix to this?
    #
    # 2) 32-bit Cygwin fucking sucks.  In many ways actually, but the real
    #    reason was the incomprehensible
    #
    #        undefined reference to `__chkstk_ms'
    #
    #    error when building with Clang.
    #
    # 3) VS 2022 isn't supported by older Boost versions.  It just doesn't
    #    work, the errors are numerous.
    #
    # 4) clang-cl on windows-2016 fails to build the latest Boost.  The error
    #    is
    #
    #        LINK : fatal error LNK1171: unable to load mspdbcore.dll (error code: 193)
    #
    #    No idea what's up with that.
