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

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.

240 ## correctly. Breaking it into two sed invocations is a workaround.
