echo dirname(realpath("f:/dir 790/asdf/"));

this prints out "f:\dir 790"
and when you do dirname() on this again, well, ...

the problem is that realpath doesn't return the trailing slash so everything else treats asdf as a file

This is not a bug but the behavior of dirname is copied from the UNIX dirname command. The semantics is that it assumes it is getting a path to a file and it strips the first filename and gives you the rest of the path. It doesn't check if the file is really a directory or not. So the following is the behavior:
dirname /tmp/ = /
dirname /tmp/foo.php = /tmp
dirname /tmo/. = /tmp (it assumes . is the filename)

It really has nothing to do with the trailing / of realpath.
