On the command line. The idea would be that make would use the CFLAGS 
environmental 
variable, see that it contains a CFLAGS make variable, and then use that make 
variable
plus the extra on the end of it.

In other words, it would force an 'override' to be set, without forcing the 
user to 
put the override in the file.

the quoting is a shell construct, forcing $(CFLAGS) to be seen as a literal. 
Why is 
it 'completely contrary to the rules that make variables use for expansion'? 
Just curious,
I don't understand.
