It is normally OK to just run 'make' after updating the sources. One
problem, however, is if one of the updated files gets a time stamp
that is newer than the previous version, but older than the corresponding
object file, it won't get re-compiled. This is in particular a problem,
if the source file in question is a header file with many dependencies.
After updating header files, you may consider touching their modification
date before running 'make'.
