My prime target was to be able to use OpenMP 3.1 which is actually only available (freely) in gcc >= 4.7. Is there a possibility to install, check and reinstall all CRAN packages in R?
I was not asking about the clang in Xcode ... my point was that not all
non-Apple versions of clang can compile quartz().
As for your question about CRAN package checks: CRAN does it daily so it
must be possible.

>> 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 clang.
