Can you show me an example of your makefile?

You must be adding the headers as prerequisites to the "all.os" (or your
equivalent); that is clearly not right.  You don't want to rebuild the
_header_ files if they change!

You need to declare that the .c files depend on the .h files (normally
this isn't the right thing to do, but in this case you'll have to do it
that way).  Use an empty rule.  Then make will imagine that the .c file
was modified whenever one of the headers was modified, and it will get
rebuilt.
