210##   -MM, not -M (despite what the docs say).  Also, it might not be
211##   supported by the other compilers which use the 'gcc' depmode.
212## - Using -M directly means running the compiler twice (even worse
213##   than renaming).

229## 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.
