[Samba] mount.cifs return code = -128

[Winkel, Richard J.]

I'm sure there are some code hackers on this list.  This snippet from 
mount.h seems incapable of
producing the value return value that I'm seeing, -128 (10000000). There 
must be something else going on but I'm flummoxed.

/* exit status - bits below are ORed */
#define EX_USAGE        1       /* incorrect invocation or permission */
#define EX_SYSERR       2       /* out of memory, cannot fork, ... */
#define EX_SOFTWARE     4       /* internal mount bug or wrong version */
#define EX_USER         8       /* user interrupt */
#define EX_FILEIO      16       /* problems writing, locking, ... 
mtab/fstab */
#define EX_FAIL        32       /* mount failure */
#define EX_SOMEOK      64       /* some mount succeeded */
