Packit 87b8d1

Packit 87b8d1
##   -MM, not -M (despite what the docs say).  Also, it might not be
Packit 87b8d1
##   supported by the other compilers which use the 'gcc' depmode.

Packit 87b8d1
##   than renaming).

## This next piece of magic avoids the "deleted header file" problem.
Packit 87b8d1
## The problem is that when a header file which appears in a .P file
Packit 87b8d1
## is deleted, the dependency causes make to die (because there is
Packit 87b8d1
## typically no way to rebuild the header).  We avoid this by adding
Packit 87b8d1
## dummy dependencies for each header file.  Too bad gcc doesn't do
Packit 87b8d1
## this for us directly.
Packit 87b8d1
## Some versions of gcc put a space before the ':'.  On the theory
Packit 87b8d1
## that the space means something, we add a space to the output as
Packit 87b8d1
## well.  hp depmode also adds that space, but also prefixes the VPATH
Packit 87b8d1
## to the object.  Take care to not repeat it in the output.
