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

## This next piece of magic avoids the `deleted header file' problem. | |
## The problem is that when a header file which appears in a .P file | |
## is deleted, the dependency causes make to die (because there is | |
## typically no way to rebuild the header). We avoid this by adding | |
## dummy dependencies for each header file. Too bad gcc doesn't do | |
## this for us directly. | |
