## This next piece of magic avoids the "deleted header file" problem.
230
231
232
233
234
## 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.
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
238
## well. hp depmode also adds that space, but also prefixes the VPATH
## to the object. Take care to not repeat it in the output.
