On one of my machines, at least (2009 MBP running OS 10.6.8), this is not so:
: [ether@tequila ]$; ls -l /usr/bin/{cc,gcc,clang,gcc-4.2}
lrwxr-xr-x 1 root wheel 7 27 Dec 2011 /usr/bin/cc -> gcc-4.2
-rwxrwxr-x 1 root admin 44430720 15 Dec 2010 /usr/bin/clang
lrwxr-xr-x 1 root wheel 7 27 Dec 2011 /usr/bin/gcc -> gcc-4.2
-rwxr-xr-x 1 root wheel 166128 23 Oct 2010 /usr/bin/gcc-4.2

: [ether@tequila ]$; clang --version
Apple clang version 1.7 (tags/Apple/clang-77) (based on LLVM 2.9svn)
Target: x86_64-apple-darwin10
Thread model: posix
: [ether@tequila ]$; gcc --version
i686-apple-darwin10-gcc-4.2.1 (GCC) 4.2.1 (Apple Inc. build 5666) (dot 3)
However, on a newer MBP (running 10.8):
: [ether@bourbon ]$; ls -l /usr/bin/{cc,gcc,clang}
lrwxr-xr-x 1 root wheel 5 22 Jul 2013 /usr/bin/cc -> clang
-rwxr-xr-x 1 root wheel 26311808 22 Jul 2013 /usr/bin/clang
lrwxr-xr-x 1 root wheel 12 22 Jul 2013 /usr/bin/gcc -> llvm-gcc-4.2
: [ether@bourbon git/misc]$; gcc --version
i686-apple-darwin11-llvm-gcc-4.2 (GCC) 4.2.1 (Based on Apple Inc. build 5658)
(LLVM build 2336.11.00)
