   source      Source file read by `PROGRAMS ARGS'.
   object      Object file output by `PROGRAMS ARGS'.
   DEPDIR      directory where to store dependencies.
   depfile     Dependency file to output.
   tmpdepfile  Temporary file to use when outputing dependencies.
   libtool     Whether libtool is used (yes/no).

 ## 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.
