`mount` command and POSIX Utility Syntax Guidelines

Hello

I have a strange problem that I can not mount a DAV folder with the 
davfs2 filesystem, because I usually keep POSIXLY_CORRECT environment 
variable set. The var allows me to keep an "aliases" file (similar to 
~/.basrc) and change it when needed if I put the file name in the ENV 
variable.

The problem is a mount sub-command invoked by `mount` (like 
`mount.davfs`), that uses glibc to parse command line, follows POSIX 
guidelines in this case and expects options and option-arguments to 
appear before any operands (which in this case are the mount device and 
the mount point).

The `mount` command, on the other hand, does not follow POSIX guidelines 
and invokes `mount.davfs` like:
   /sbin/mount.davfs \
          https://storage-file-eu.gmx.com/ \
          ./gmx-file-storage \
          -o rw,nosuid,nodev,noauto,user,_netdev,exec
That is, with the options after the operands.

Subsequently the mount command returns and error when mounting my DAV 
folders. Can the `mount` please be fixed to follow POSIX Utility Syntax 
Guidelines ? At least when POSIXLY_CORRECT is set in the environment ?

I have Slackware 13.37 updated from Slackware-current, 32 bit.
