Comment 1

[Mike Hommey [:glandium]]

Attachment: Bug 1840530 - Enable filesystem support in libc++ for mingw.

clang trunk recently removed the granularity between fstream and
filesystem, and to have fstream, one needs to enable filesystem, now.

Comment 2

[Tom Ritter [:tjr] (OOTO until mid-August)]

If there are mingw clang bugs, could you have them all block mingw-clang - it will help Tor Browser folks when they are upgrading compilers to be able to reference the changes easier. Thanks!
