Hi

On a Cygwin/win7/x86_64 platform with , one gets this error message when
compiling the following source with -std=c++11 while it compiles fine with
-std=gnu++11

$ cat foo.c
#include <stdio.h>

int main(void) {
        char buf[10];
        snprintf(buf, 10, "%i", 0);
        printf("buf=%s\n", buf);
        return 0;
}

$ gcc -xc -std=c90 -c foo.c
$ gcc -xc -std=c89 -c foo.c
$
$ g++ -xc++ -std=c++11  -c foo.c
foo.c: In function 'int main()':
foo.c:5:27: error: 'snprintf' was not declared in this scope
  snprintf(buf, 10, "%i", 0);

$
$ g++ -xc++ -std=gnu++11  -c foo.c
