TeX has 2 primitives that are used with errors and warnings.

  \errmessage{...}  causes TeX to print the argument to screen,
               then stops and provides an interactive interface 
               for how to proceed.

  \message{...}    just prints its argument into the log.

If you really want to stop at all warnings --- 
beware, there are many that are only printed in the .log file
then you could experiment with:


within your document, or within packages that you write.

This makes a local reassignment, so can be scoped to work
just within appropriate TeX groupings  { .... }
 or  \begingroup .... \endgroup   contexts.
