[Rd] Tip for removing -c99 when compiling with icc

[Bjørn-Helge Mevik]

Dear developeRs,

As of icc 10, the -c99 option is deprecated, and generates a lot of
warnings when compiling R or R packages.

If you use CC="icc -std=c99" instead of just CC="icc", R's configure
will not add the -c99 option, and the code seems to compile and run just
fine.

(Please don't hesitate to let me know if this is a bad idea. :-)
