Could you try this:

I just noticed this (info "(make) Suffix Rules"):

     Suffix rules cannot have any prerequisites of their own.  If they
  have any, they are treated as normal files with funny names, not as
  suffix rules.  Thus, the rule:

       .c.o: foo.h
               $(CC) -c $(CFLAGS) $(CPPFLAGS) -o $@ $<

  tells how to make the file `.c.o' from the prerequisite file `foo.h',
  and is not at all like the pattern rule:

       %.o: %.c foo.h
               $(CC) -c $(CFLAGS) $(CPPFLAGS) -o $@ $<

  which tells how to make `.o' files from `.c' files, and makes all `.o'
  files using this pattern rule also depend on `foo.h'.

That means the fix mentioned above must have been ineffective...

Thanks,
Ludo’.
