Naming Scheme for Predefined Macros

The naming scheme for predefined macros has been rationalized, and the implicit rules have been rewritten to reflect the new scheme. The macros and implicit rules are upward compatible with existing makefiles.

Some examples include the macros for standard compilations commands:

LINK.c

which is a standard cc command line for producing executable files.

COMPILE.c

which is a standard cc command line for producing object files.
