The sensible way to handle this is not to put more than one version of 
gcc in your path.  This is true on Linux too - I have "normal" system 
gcc on the path, and dozens of different gcc's (for a variety of 
targets) in directory trees that are not on my path.  My Makefiles for 
project specify exactly where to find the relevant compiler for the 
project, and all other files, executables, headers, libraries, etc., are 
found based on that path.  It works in exactly the same way on Linux and 
Windows.

Of course, I know you Bart will run away screaming at the mention of 
"Makefile", but for almost everyone else who does C programming, it is 
convenient tool.
