samba - Jul 2003 - smbfs: bad mount msg

VMware: 4.0.0
Host: Win2k
Guest: RH9

At level 3 I issue (one line, no inappropriate spaces):

  mount -t smbfs -o user,noauto,dmask=777,fmask=777,
  username=xx,password=yy //box/share /mnt/share

I get these messages:

  Jul 12 05:56:26 VmLinux kernel: smbfs: Unrecognized mount option noexec
  Jul 12 05:56:26 VmLinux rc: Starting smbfsmnt:  succeeded

The mount is successful.  What is the significance of the first message?

Thanks for your help.

Mike.
