Usage: depcomp [--help] [--version] PROGRAM [ARGS]

Run PROGRAMS ARGS to compile a file, generating dependencies as side-effects.

Environment variables:

depmode     Dependency tracking mode.
source      Source file read by `PROGRAMS ARGS'.
object      Object file output by `PROGRAMS ARGS'.
DEPDIR      directory where to store dependencies.
depfile     Dependency file to output.
tmpdepfile  Temporary file to use when outputing dependencies.
libtool     Whether libtool is used (yes/no).

gcc) ## 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.
