I know that newer Microsoft compilers tend to drop support for older 
operating systems, and often that means the binaries simply won't work 
on those operating systems.  (Yes, technically it's the libraries that 
break the older code.)

Are Apple's compilers the same?  Or do they tend to support all the old 
versions of OS X?
