./PROBLEMS to mention workarounds for ULTRIX build problems.

appreciated.

NOTE: building non-shared doesn't come with this problem.

* ULTRIX build fails with shell errors, such as "bad substitution"

  and "test: argument expected"

The problem is caused by ULTRIX /bin/sh supporting only original

Bourne shell syntax/semantics, and the trouble is that the vast

majority is so accustomed to more modern syntax, that very few

people [if any] would recognize the ancient syntax even as valid.

This inevitably results in non-trivial scripts breaking on ULTRIX,

and OpenSSL isn't an exclusion. Fortunately there is workaround,

hire /bin/ksh to do the job /bin/sh fails to do.

1. Trick make(1) to use /bin/ksh by setting up following environ-

   ment variables *prior* you execute ./Configure and make:

	PROG_ENV=POSIX

	MAKESHELL=/bin/ksh

	export PROG_ENV MAKESHELL

   or if your shell is csh-compatible:

	setenv PROG_ENV POSIX

	setenv MAKESHELL /bin/ksh

2. Trick /bin/sh to use alternative expression evaluator. Create

   following 'test' script for example in /tmp:

	#!/bin/ksh

	${0##*/} "$@"

   Then 'chmod a+x /tmp/test; ln /tmp/test /tmp/[' and *prepend*

   your $PATH with chosen location, e.g. PATH=/tmp:$PATH. Alter-

   natively just replace system /bin/test and /bin/[ with the

   above script.
