What version of gcc are you using?
In the script that creates dependencies there is some filtering of $(CC)
-E (I believe), because Tom was attempting to be compatible, and not use
the gcc -MM flags.
Anyway, gcc changed the output, to include the directory name, which was
not getting filtered out.
Since most systems update the mtime of a directory when it's contents
change, this causes a dependency problem.

Anyway, if you look into:
src/build-tools/Makefiles/cpp-to-includes.sed
(I'm not sure where this is in the revc tools, I'm following tla/baz here)

Anyway, in that file you need a line like this:
/\/\/$/d

(The bogus lines end in //, so you just remove lines that look like that).
