Comment(by ryandesign@…):

 With Xcode 4.4 on Mountain Lion, /usr/bin/cc is a link to Apple Clang 4.0,
 while /usr/bin/gcc is a link to llvm-gcc 4.2. This seems designed to
 guarantee that /usr/bin/gcc actually behaves mostly like the GNU C
 compiler, whereas /usr/bin/cc is merely a C compiler, that does not
 necessarily conform to the GNU C compiler's quirks. This distinction seems
 valuable.
