1.	Indent four spaces (not three and not tabs).

    2.	Literals used (other than 0 or 1).

    3.	NULL used in several places.

    4.  Put braces on their own lines like this:

	    if (condition)
	    {

	    }

	Avoid this style:

	    if (condition) {

	    }

    5.	Makedepend utility was made the default depend
	utility on some platforms. The deafault should be
	"mu depend".

    6.	Regression tests should only print this:

	    "+++++ passed all tests"

	Extraneous output should be removed.
