title: Default rules in Make
body: <p>Is there a mechanism in make to allow for default global implicit rules that are available anywhere, similar to the built-in rules?</p>
  
  <p>Make provides some built-inimplicit rules for compiling C/C++/Fortran files, without even requiring a <code>Makefile</code> for simple cases.  However, when compiling other languages (e.g. Go programming language files), a <code>Makefile</code> is always required.  I would like to extend my Makeenvironment to have implicit rules available by default.</p>
