--- Comment #4 from Lancelot SIX <lsix at lancelotsix dot com> ---
I had a look a t various compiler versions.

- gcc-7.5 does not have std::filesystem support available, so if we want to
keep supporting this compiler, we can't move to remove_all.
- gcc-8 has std::filesystem, but using it require using "-lstdc++fs". 
Supporting this compiler would require an extra configure step to check if this
flag is required.
- starting gcc-9, std::filesytem is available without extra compiler flags.

For now, I think we will try to maintain gcc-7.5 compatibility as it is still
used.  This will need to be revisited at some point.
