The very first line in the recipe command in that example is:

        set -e; ...

This means that any command that fails in the recipe command immediately exits that command with an error.  There is no need to check every command individually for errors.

I have noticed the following code fragment in a recipe which is mentioned in the section “Generating prerequisites automatically” of the documentation.

         $(CC) -M $(CPPFLAGS) $< > $@.$$$$; \

The semicolon indicates at the end that the return value is ignored there. I imagine that further data processing should usually only be performed if this command succeeded.
Would you like to improve the exception handling for such a situation?
