 Please scratch that, I've downloaded the 8.1 package from SourceForge and
it doesn't have the library neither. In fact, it still has the bug which
prevents you from even compiling any code including <filesystem>, that I
had reported to Debian[1] and which got fixed there -- allowing me to go as
far as getting the link errors now when using the cross-compiler. With the
native compiler, it still stops at compile-time...

 It simply looks that it's not available in gcc 8 for MSW platform.
According to https://gcc.gnu.org/bugzilla/show_bug.cgi?id=78870 it
should/will be available in gcc 9, however, and I've just opened another
Debian bug[2] to ask them to use a non-default configure option to enable
it.
