If you want to be really portable to Solaris, don't put the ; do on
the same line:
the extra-portable syntax is

          for i in `get_menu_entries "$1"`
          do

You're facing an uphill battle, though, if you really want
to support classic sh.  Not many people understand or care.
You'll probably need to set up a nightly build-and-test
on Solaris to keep the code from rotting.

BTW, here's a great book about classic sh programming:
  "Portable Shell Programming" by Bruce Blinn
It's like the "K&R" of shell programming.
