150 ## (see the conditional assignment to $gccflag above).
151 ## There are various ways to get dependency output from gcc. Here's
152 ## why we pick this rather obscure method:
153 ## - Don't want to use -MD because we'd like the dependencies to end
154 ## up in a subdir. Having to rename by hand is ugly.
155 ## (We might end up doing this anyway to support other compilers.)
156 ## - The DEPENDENCIES_OUTPUT environment variable makes gcc act like
157 ## -MM, not -M (despite what the docs say). Also, it might not be
158 ## supported by the other compilers which use the 'gcc' depmode.
159 ## - Using -M directly means running the compiler twice (even worse
160 ## than renaming).

177 ## This next piece of magic avoids the "deleted header file" problem.
178 ## The problem is that when a header file which appears in a .P file
179 ## is deleted, the dependency causes make to die (because there is
180 ## typically no way to rebuild the header). We avoid this by adding
181 ## dummy dependencies for each header file. Too bad gcc doesn't do

187 ## to the object. Take care to not repeat it in the output.
