| ## - Don't want to use -MD because we'd like the dependencies to end | |
| ##   up in a subdir.  Having to rename by hand is ugly. | |

| ##   -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. | |
