Unfortunately, we don't distinguish between the macro used to identify 
gcc, and the macro used to identify the GNU C language implemented by 
gcc.  We use the same macro for both purposes.  Since it is reasonable 
for any compiler to implement the GNU C language, and because any such 
compiler must define the __GNUC__ macro, I don't believe we have any 
credible argument for restricting other compilers from defining __GNUC__.
