Here's two more diffs...

The first fixes a warning from gcc about the assignment within the condition.
The extra set of parens should not make a difference, but with -Werror, they
are necessary.

The second fixes an "ln -s" invocation that assumes the current directory is
implicitly the target if not specified.  Not true in all cases, and again, it
should not make a difference except to those implementation that it does.
