gcc48: undefined symbol for toupper(int) when compiled as C11

[davydden@…]

The simple example which uses toupper(int)

#include <stdio.h>
#include <ctype.h>
int main ()
{
  int i=0;
  char str[]="Test String.\n";
  char c;
  while (str[i])
  {
    c=str[i];
    putchar (toupper(c));
    i++;
  }
  return 0;
 }

does link via

g++-mp-4.8 main.cc -o main

but does not when invoking C11:

g++-mp-4.8 -std=c++11 main.cc -o main

Undefined symbols for architecture x86_64:
  "toupper(int)", referenced from:
      _main in ccWjHauc.o
ld: symbol(s) not found for architecture x86_64
collect2: error: ld returned 1 exit status

Macports was build on Xcode 5 under 10.9. I am not sure if this is related to gcc4.8, but this behavior was not the case for the previous Xcode (4.6) and OS-X Mountain Lion.
