10.960 rmdir

POSIX specification:
https://pubs.opengroup.org/onlinepubs/9699919799/functions/rmdir.html

Gnulib module: rmdir

Portability problems fixed by Gnulib:

• This function is declared in different header files (namely, <io.h> or <direct.h>) on some platforms: mingw, MSVC 14.
• This function mistakenly removes a directory with rmdir("dir/./") on some platforms: Cygwin 1.5.x.
• This function fails with EINVAL instead of the expected ENOTDIR for rmdir("file/") on some platforms: mingw, MSVC 14.

Portability problems not fixed by Gnulib:

• When rmdir fails because the specified directory is not empty, the errno value is system dependent.
• POSIX requires that rmdir("link-to-empty/") remove empty and leave link-to-empty as a dangling symlink. This is counter-intuitive, so some systems fail with ENOTDIR instead: glibc
