#41020: undefined symbol for toupper(int) when compiled as C11
------------------------+--------------------------------
 Reporter:  davydden@…  |      Owner:  macports-tickets@…
     Type:  defect      |     Status:  new
 Priority:  Normal      |  Milestone:
Component:  ports       |    Version:  2.2.1
 Keywords:              |       Port:  gcc
------------------------+--------------------------------
 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.
