[Rd] compiler specific flags : -std=c++0x

[Romain Francois]

Hello,

We'd like to use the flag -std=c++0x to take advantage of features of 
the forthcoming C++0x standard that is already partly implemented by the 
GCC >= 4.3

R CMD check warns about the flag because it is non portable. Is there a 
way to turn the warning off, considering that we do test that the 
compiler is indeed GCC >= 4.3 as part of our configure script and we 
only add the flag in that case.

Romain
