## 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). Also, it might not be |
## supported by the other compilers which use the 'gcc' depmode. |
## - 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. |
## Some versions of gcc put a space before the ':'. On the theory |
## that the space means something, we add a space to the output as |
## well. hp depmode also adds that space, but also prefixes the VPATH |
## to the object. Take care to not repeat it in the output. |
## Some versions of the HPUX 10.20 sed can't process this invocation |
## correctly. Breaking it into two sed invocations is a workaround. |
