> Great! Please read https://gcc.gnu.org/onlinedocs/libstdc++/manual/appendix_contributing.html especially the part about legal paperwork.

Do you mean the part about legal paperwork in
https://gcc.gnu.org/contribute.html ?

> No. Just look at the existing code and figure out what the equivalent code would be for Windows, and write an alternative implementation e.g. replace calls to POSIX stat() with whatever Windows uses to query file properties, and replace calls to POSIX chmod with whatever Windows uses to change file permissions.

And can I look at how boost::filesystem does this?
