Gnulib module: rmdir

Portability problems fixed by Gnulib:
@itemize
@item
This function is declared in different header files (namely, @code{<io.h>} or
@code{<direct.h>}) on some platforms:
mingw, MSVC 14.
@item
This function mistakenly removes a directory with
@code{rmdir("dir/./")} on some platforms:
Cygwin 1.5.x.
@item
This function fails with @code{EINVAL} instead of the expected
@code{ENOTDIR} for @code{rmdir("file/")} on some platforms:
mingw, MSVC 14.
@end itemize

Portability problems not fixed by Gnulib:
@itemize
@item
When @code{rmdir} fails because the specified directory is not empty, the
@code{errno} value is system dependent.
@item
POSIX requires that @code{rmdir("link-to-empty/")} remove @file{empty}
and leave @file{link-to-empty} as a dangling symlink.  This is
counter-intuitive, so some systems fail with @code{ENOTDIR} instead:
glibc
