fchdir: another mingw fix canonicalize_file_name does not understand drive letters or backslash. The only reason openat required it was to make fchdir get the canonical name of a directory. But we can do the same trick with chdir and getcwd. With this fix, fchdir(open("..",O_RDONLY)) finally does the right thing on mingw. * modules/fchdir (Depends-on): Drop canonicalize-lgpl. * lib/fchdir.c (get_name): New helper method; skips canonicalize on mingw (where it has not yet been ported), and make it optional elsewhere. (_gl_register_fd): Use it. Signed-off-by: Eric Blake <ebb9@byu.net>
