You don't need a Makefile to perform simple tasks, because Make knows
a lot of built in rules out of the box. For example, to compile a .c
source file foo.c into a program foo, all you need is say "make -k foo",
and Make will do it even without a Makefile.

Customize the variable compile-command.

Where did you put this and how did you use it?
