## There are various ways to get dependency output from gcc. Here's
120
## why we pick this rather obscure method:
121
## - Don't want to use -MD because we'd like the dependencies to end
122
## up in a subdir. Having to rename by hand is ugly.
123
## (We might end up doing this anyway to support other compilers.)
124
## - The DEPENDENCIES_OUTPUT environment variable makes gcc act like
125
## -MM, not -M (despite what the docs say).
126
## - Using -M directly means running the compiler twice (even worse
127
## than renaming).

## This next piece of magic avoids the `deleted header file' problem.
145
## The problem is that when a header file which appears in a .P file
146
## is deleted, the dependency causes make to die (because there is
147
## typically no way to rebuild the header). We avoid this by adding
148
