Packit 679830

Packit 679830
##   -MM, not -M (despite what the docs say).  Also, it might not be
Packit 679830
##   supported by the other compilers which use the 'gcc' depmode.

Packit 679830

## This next piece of magic avoids the "deleted header file" problem.
Packit 679830
## The problem is that when a header file which appears in a .P file
Packit 679830
## is deleted, the dependency causes make to die (because there is
Packit 679830
## typically no way to rebuild the header).  We avoid this by adding
Packit 679830
## dummy dependencies for each header file.  Too bad gcc doesn't do
Packit 679830
## this for us directly.
Packit 679830
## Some versions of gcc put a space before the ':'.  On the theory
Packit 679830
## that the space means something, we add a space to the output as
Packit 679830
## well.  hp depmode also adds that space, but also prefixes the VPATH
