Just a few problems with this solution:

	1. It's a pain in the *ss to change all the makefiles

	2. Error messages from the cc tmp.c will point to the wrong line numbers
	
	3. A source level debugger would require the tmp.c file to stay around
	   which would require you the use a different name for each file.  If
	   you chose to add a letter to the begining (like Tfoo.c), you run the
	   risk of making a file name that is too long for the system.
