[R] rtools fstream error

Hi,

when writing a simple cpp function to be run in R I obtain a compilation error
as soon as I include fstream. Any hints of what goes wrong and how to fix it?
It's Windows 7 64-bit, R-3.1.2 and Rtools32. An example to recreate the
error:

    #include <R.h>
    #include <Rdefines.h>
    #include <fstream>
    using namespace std;
    
    extern "C" SEXP test(SEXP x) {
      SEXP result;
      
      PROTECT(result = allocVector(REALSXP,1));
      REAL(result)[0] = REAL(x)[0]*5;
    
      UNPROTECT(1);
      return result;
    }

Output:

[R] rtools fstream error

Try adding the line
  #define R_NO_REMAP
to the top of your file (before any #include's) so the R
include files don't define length(x).

[R] rtools fstream error

Thank you, it worked. 
For completeness, had to add Rf_ in front of allocVector (and possibly any other
function from Rdefines.h)
