R :: override C compiler with Makevars

Question

Our R installation defines:

R$HOME/etc/Makeconf that CC = gcc -std=gnu99 

I have one specific package (a combination of C ++ and C code) that needs to be compiled with

  CC = gcc  

without -std=gnu99

As I understand it, I have three ways to do this:
1) in the system, edit R $ HOME / etc / Makeconf
2) for each user, play with ~ / .R / Makevars
3) for each package, set PACKAGE / src / Makevars

Even if 1 and 2 are not what I want, I tested 3 options using 1 and 2

R CMD INSTALL -l pack.tgz OK "gcc -std = gnu99" is replaced by "gcc"

But when using the approach PACKAGE/src/Makevarsit fails

I have to admit that I was lost at this moment, where should I look?

. R- GCC . , Makevars

, PACKAGE/src/Makevars CC = , .
