          207 ##   up in a subdir.  Having to rename by hand is ugly.
          208 ##   (We might end up doing this anyway to support other compilers.)
          209 ## - The DEPENDENCIES_OUTPUT environment variable makes gcc act like
          210 ##   -MM, not -M (despite what the docs say).  Also, it might not be
          211 ##   supported by the other compilers which use the 'gcc' depmode.
          212 ## - Using -M directly means running the compiler twice (even worse
          213 ##   than renaming).

          229 ## This next piece of magic avoids the "deleted header file" problem.
          230 ## The problem is that when a header file which appears in a .P file
          231 ## is deleted, the dependency causes make to die (because there is
          232 ## typically no way to rebuild the header).  We avoid this by adding
          233 ## dummy dependencies for each header file.  Too bad gcc doesn't do
          234 ## this for us directly.
          235 ## Some versions of gcc put a space before the ':'.  On the theory
          236 ## that the space means something, we add a space to the output as
          237 ## well.  hp depmode also adds that space, but also prefixes the VPATH
          238 ## to the object.  Take care to not repeat it in the output.
