Automatic dependency tracker vanished - why?

[Markus Werle]

Hi!

Again the beginner gets surprised:
Automake used to be fine in dependency tracking:
changing any source file made make to recompile the files,
since directory .deps contained the correct information.

Now - after some changes in Makefile.am I find that the files
in .deps only contain the line
# dummy

Why? What went wrong?

I made the aclocal && autoconf && automake && autoheader
Any detail I missed?
