Comment (by rmottola):

 Just tried updating now... and of course it fails
 {{{
 -- Performing Test std_filesystem_with_libfs - Failed
 CMake Error at cmake/StdFilesystem.cmake:22 (message):
   Toolchain doesn't support std::filesystem with nor without -lstdc++fs
 Call Stack (most recent call first):
 }}}


 however I also see lots of errors this time (I don't know if they happened
 last time) which look similar to what I got when building clang:
