[Rd] darwin build with latest gcc from apple

[Stefano Iacus]

R-devel configs and build fine on both configurations below.
It would be nice to test it on Panther eventually. A great thank goes 
from my side to Kurt for this configure version.

I configure with:

./configure --enable-R-shlib --with-blas='-framework vecLib' 
--with-lapack 
--with-tcl-config=/Library/Frameworks/Tcl.framework/tclConfig.sh 
--with-tk-config=/Library/Frameworks/Tk.framework/tkConfig.sh 
--with-aqua

and you should eventually change the tcl/tk config files
