 ## There are various ways to get dependency output from gcc.  Here's

 ## why we pick this rather obscure method:

 ## - Don't want to use -MD because we'd like the dependencies to end

 ##   up in a subdir.  Having to rename by hand is ugly.

 ##   (We might end up doing this anyway to support other compilers.)

 ## - The DEPENDENCIES_OUTPUT environment variable makes gcc act like

 ##   -MM, not -M (despite what the docs say).

 ## - Using -M directly means running the compiler twice (even worse

 ##   than renaming).

 ## This next piece of magic avoids the `deleted header file' problem.

 ## The problem is that when a header file which appears in a .P file

 ## is deleted, the dependency causes make to die (because there is

 ## typically no way to rebuild the header).  We avoid this by adding

 ## dummy dependencies for each header file.  Too bad gcc doesn't do

 ## this for us directly.
