/* This one is problematic. If you open() a directory with the
MiNTLib you can't detect from errno if it is really a directory
or if the file simply doesn't exist. You'll get ENOENT
("file not found") in either case.
Defining EISDIR as ENOENT is actually a bad idea but works fine
in general. In praxi, if code checks for errno == EISDIR it
will attempt an opendir() call on the file in question and this
call will also file if the file really can't be found. But
you may get compile-time errors if the errno checking is embedded
in a switch statement ("duplicate case value in switch").
Anyway, here the define works alright. */
