Generic Makefile for building dynamic C programs. If you edit a .h file, Make will rebuild only the C-related, object files that include that header. Similarly, make will only rebuild object files and the binary with the minimal amount of recompiling. Simple valgrind example and "clean" as well.

Add to .gitignore:

*.o
*.d
<OBJ>
