That's only the common sense attitude!  8-}

Encore's UMAX4.2 (loosely based upon 4.2BSD) included the BRL
version of the SysV3.2 /bin/sh.  Encore's 4.3BSD release seems to
have had this replaced by the older 4.3BSD /bin/sh.  A note in one
of their documents says to check (and change) all the shell scripts
and Makefiles on your machine to "assure BSD compatibility".

The SysV3.2 shell is still available in "/usr/old/sh".  And, on a
positive note, they do the world one favor and distribute ksh as
a standard part of every system.  That, at least, can be used to
replace /bin/sh (with just the loss of "^" or so).  Actually, ksh
appears to be the 1985 version (which is about the time when the
BRL shell was incorporated into UMAX4.2).  Oops.
