Apple calls its compiler gcc. But yes it is llvm based.
mymacmini:usbutils xiaofanc$ gcc -v

I see what you mean. I do not know how to do that though since
I know very little of autotools.

I see. The following patch will still work for Mac OS X.
But I think you want a better patch. Hopefully someone
more capable can come out with a better patch.
