commit 7ff2eef926f933c79c3913c18f9403a4a987756b
Author: Eli Zaretskii <address@hidden>
Commit: Eli Zaretskii <address@hidden>
Fix the MS-Windows build broken by recent errno changes
* src/fileio.c (file_directory_p): If the file exists, but is
not a directory, set errno to ENOTDIR, like the Posix branch
does; openp expects that.
