|
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).

|
|
## 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

|

## 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

## typically no way to rebuild the header). We avoid this by adding
