Subject: [PATCH] Portability
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Applied patch from Emil Sköldberg.

Replace 'test ... == ...' with 'test ... = ...',
since [quoted from pkgsrc error message]:

The "test" command, as well as the "[" command, are not required to know
the "==" operator. Only a few implementations like bash and some
versions of ksh support it.

When you run "test foo == foo" on a platform that does not support the
"==" operator, the result will be "false" instead of "true". This can
lead to unexpected behavior.
