//////////////////////////////////////////////////
This program runs fine on Windows, but throws on POSIX.
This is because POSIX opendir is defined to return ENOENT if the argument is an
empty string:
> [ENOENT] A component of dirname does not name an existing directory or
> dirname is an empty string.
Although the call to dirEntries can be changed to dirEntries("."), this has the
unpleasant effect of prepending "./" to all paths returned by dirEntries. It is
additionally a portability hazard (code that works on one OS but not another).
I thus propose to make dirEntries("") call opendir(".") under the hood.
