Check out this page on Paul's web site:
    http://make.mad-scientist.net/autodep.html#advanced

For at least the last 7 years, gcc actually has additional options -MF
-MP and -MT which practically eliminate the need for the sed scripting
described on that page; concentrate on the underlying concept of
generating as part of compilation and then work out the best way to do
that on your system.
