Hi Jean-Michel,

It sounds like "make depend" somehow isn't working for you.  If you
build with the commands:

  ../../../genmake2 [...OPTIONS...]
  make depend
  make

then the second step ("make depend") should create a list of file
dependencies at the end of your Makefile.  Its that list of dependencies
that helps "make" determine what needs to be rebuilt.  So, did you skip
the "make depend" stage?  Or do we have a problem where one of the
"makedepend" programs isn't working correctly?

Ed
