COMPATIBILITY ISSUES
     To retain some backward compatibility to the Bourne shell, certain Korn
     shell features are controlled by how the shell is invoked and/or the
     current value of the environment variable _XPG.

     When the shell is invoked as "sh", the following features are performed
     only when the current value of the _XPG variable is equal to 1 (one):

          - command substitution of the form "$( command )"
          - arithmetic expression of the form "$(( expression ))"
          - tilde expansion of pathnames
          - parameter $0 within a function call is the name of the
            invoking shell script
          - unsetting variables, not previously set or null, returns 0

So touch_files_reexec tries to exec the function touch_files_reexec.
I've opened a support call with SGI to find out why they did the
above. They do have /bin/bsh which is the Bourne Shell and it behaves
as one would expect.
