static linking can work. dynamic linking could not.

I really doubt anything before Windows XP is supported really.
The libstdc++ changes which added Windows support for std::filesystem broke
this.

by the way, throwing EH on windows ME results in a direct crash. I do not know
why.

I have no interest in making the filesystem library work on old versions of
Windows. If we expect libstdc++ to be usable there, that function should just
report an error on old versions.

I do not know whether there is a setting to disable filesystem in dll when we
build GCC.

--disable-libstdcxx-filesystem-ts does not seem to work.

Just disable it.

And do not define feature testing macro __cpp_lib_filesystem

Windows ME has not been supported by Microsoft since 2006, this is going to
close as won't fix.

Windows XP is bare min that is supported by newer GCC's.
