[R-SIG-Mac] gcc 4.2 and the Accelerate framework

[Kjell Konis]

In case you hadn't noticed, the 10.4.8 update "Adds support on Intel- 
based Macs for multiple cores to LAPACK and BLAS routines in the  
Accelerate framework; the maximum number of threads used by  
Accelerate BLAS routines is now limited by the environment variable  
VECLIB_MAXIMUM_THREADS; addresses an issue with some complex BLAS  
routines in the Accelerate framework that were encountering an  
illegal instruction." (http://docs.info.apple.com/article.html? 
artnum=304200)

I would like to try it out but currently I have gcc 4.2 installed.  
Can I build R with gcc 4.2 and link it against the Accelerate  
framework or do I still need to build with gcc 4.0?
