Three recent changes to mv caused problems when I tried to compile it:

1.  It erroneously called 'getopt' instead of 'getopt_long', so the long
option names weren't recognized.

2.  Initialization of automatic structures is not supported by many C
compilers.

3.  EACCESS is called EACCES on at least some System V-derived systems.

Below are fixes for these problems.

Also, perhaps the usage message should mention the long option names.
