Testing m4-1.4.21 on Mac OS X 10.6.8, Snow Leopard

Hello!

Testing M4 on this ancient OS produces some trouble, probably because of =
too old shell interpreters:

	=E2=80=A2 pete 847 /\ /bin/sh --version
	  GNU bash, version 3.2.48(1)-release (x86_64-apple-darwin10.0)

	=E2=80=A2 pete 855 /\ /bin/zsh --version
	  zsh 4.3.9 (i386-apple-darwin10.0)

/bin/sh is /bin/bash and /bin/csh is /bin/tcsh. When the test procedure =
starts to execute tests with ksh it gets stuck (from pstree):

I had to 'kill -1 43412' and another time when ksh was involved, in =
test-option-parser.sh. Here is an excerpt from test-suite.log (already =
sent by eMail):

	~> func_quote expand: non-existent-2: "$empty" "${empty}"

	FAIL test-funclib-quote.sh (exit status: 1)

Here are snapshots from the directory:

  drwxr-xr-x  11 macports  wheel   60622 19 Feb 22:35 .
  -rw-r--r--   1 macports  wheel    1877 19 Feb 22:35 =

    *kill -1*
  -rw-r--r--   1 macports  wheel    5858 19 Feb 23:03 =
test-option-parser.sh.log

You can see that I had some perseverance while testing=E2=80=A6 Build =
and tests were done from the MacPorts package manager.

I am concerned for you to enjoy yourselves within the limits of British =
decency.
