Packit 712bc5
##   (We might end up doing this anyway to support other compilers.)
Packit 712bc5
## - The DEPENDENCIES_OUTPUT environment variable makes gcc act like
Packit 712bc5
##   -MM, not -M (despite what the docs say).  Also, it might not be
Packit 712bc5
##   supported by the other compilers which use the 'gcc' depmode.

Packit 712bc5

Packit 712bc5
## This next piece of magic avoids the "deleted header file" problem.
Packit 712bc5
## The problem is that when a header file which appears in a .P file
Packit 712bc5
## is deleted, the dependency causes make to die (because there is
Packit 712bc5
## typically no way to rebuild the header).  We avoid this by adding
Packit 712bc5
## dummy dependencies for each header file.  Too bad gcc doesn't do
Packit 712bc5
## this for us directly.
Packit 712bc5
## Some versions of gcc put a space before the ':'.  On the theory
Packit 712bc5

Packit 712bc5
