## 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.
