## This next piece of magic avoids the "deleted header file" problem.
|
|
230 |
## The problem is that when a header file which appears in a .P file
|
|
231 |
## is deleted, the dependency causes make to die (because there is
|
|
232 |
## typically no way to rebuild the header). We avoid this by adding
|
|
233 |
## dummy dependencies for each header file. Too bad gcc doesn't do
|
|
234 |
## this for us directly.
|
|
235 |
## Some versions of gcc put a space before the ':'. On the theory
|
|
236 |
## that the space means something, we add a space to the output as
|
|
237 |
## well. hp depmode also adds that space, but also prefixes the VPATH
|
|
238 |
## to the object. Take care to not repeat it in the output.
|
|
239 |
## Some versions of the HPUX 10.20 sed can't process this invocation
|
|
240 |
## correctly. Breaking it into two sed invocations is a workaround.
