We know (I believe it has been mentioned here before).  But please 
remember that only the Apple clang is easy to use (does your self-build 
compile the quartz device? -- mine did not), and Apple lags a long way 
behind.  The current Xcode version says it is '3.2svn' but lacks even 
3.1 features such as AddressSanitizer.  We will see what Xcode 5 brings 
when it is released.

I don't think people appreciated Simon's comments about the stability 
needed.  If you can check all of CRAN with no more than 10 issues with 
gcc 4.7 or 4.8, then let us know.  That is about where we are with 
llvm-gcc 4.2 and clang 3.2- from Xcode 4.6.3.  When I tried 4.7.x prior 
to R 3.0.0 I had over 50 failures (and CRAN is reqularly checked with 
4.7.x on other platforms).

And we are only in that good a state because a lot of (literally) 
thankless work has been done to get CRAN/BioC packages to compile with
