## There are various ways to get dependency output from gcc. Here's
65
## why we pick this rather obscure method:
66
## - Don't want to use -MD because we'd like the dependencies to end
67
## up in a subdir. Having to rename by hand is ugly.
68
## (We might end up doing this anyway to support other compilers.)
69
## - The DEPENDENCIES_OUTPUT environment variable makes gcc act like
70
## -MM, not -M (despite what the docs say).
71
## - Using -M directly means running the compiler twice (even worse

## This next piece of magic avoids the `deleted header file' problem.
89
## The problem is that when a header file which appears in a .P file
90
## is deleted, the dependency causes make to die (because there is
91
## typically no way to rebuild the header). We avoid this by adding
92
## dummy dependencies for each header file. Too bad gcc doesn't do
93
## this for us directly.
96
## Some versions of gcc put a space before the `:'. On the theory
97
## that the space means something, we add a space to the output as
