  19 # Here's the bug: makedepend will prefix VPATH to the object file name,
  20 # thus the second make will invoke depcomp with object='../../src/foo.o',
  21 # causing errors such as:
  22 # touch: cannot touch `../../src/.deps/foo.TPo': No such file or directory
  23 # makedepend: error:  cannot open "../../src/.deps/foo.TPo"
  24 # ../../depcomp: line 560: ../../src/.deps/foo.TPo: No such file or directory
  25
  26 # We include subfoo only to be sure that we don't remove too much
  27 # from the object file name.
