Makefile for netdemo

[gene.smith at siemens.com (Smith, Gene)]

This is related to the other Makefile/make questions that are floating 
around today. I have been trying to understand how the simple netdemo 
builds and I have a question.

When the compiler or linker is invoked (actually both via gcc) the make 
file (and/or its many included helper files) uses variables like these 
to run the programs:

$(COMPILE.c)
$(LINK.c)

I can see with debug -d that these do evaluate to the correct program 
(in my case powerpc-rtems-gcc) but I can't find where these values 
COMPILE.c, LINK.c are defined.

Thanks,
