[Bug c/29674] New: strtok_r function prototype does not match function definition

[brandon at rioja dot us]

Sees:
When compiling using the -Wconversion flag the strtok_r the comppiler complains
with a 
"""
warning: passing argument 2 of ‘__strtok_r_1c’ with different width due to
prototype
"""
Expects:
No warning when the -Wconversion option is specified

".deps/hello.Tpo"; exit 1; fi
hello.c: In function ‘main’:
hello.c:10: warning: passing argument 2 of ‘__strtok_r_1c’ with different width
due to prototype
gcc -Wconversion -g -O2   -o hello  hello.o  
aaaa
[EMAIL PROTECTED] test]$ 

For source code hello.c:
#include <unistd.h>
#include <stdio.h>
#include <string.h>

int main()
{
  const char* delim = "xy";
  char str[] = "aaaaxbbbbyccccc";
  char *saved;
  printf("%s\n",strtok_r(str, delim, &saved));
  return 0;
}

Works for strtok():
Regular strtok()'s function prototype matches its definiton.

#include <unistd.h>
#include <stdio.h>
#include <string.h>

int main()
{
  const char* delim = "xy";
  char str[] = "aaaaxbbbbyccccc";
  printf("%s\n",strtok(str, delim));
  return 0;
}

Note: 
Could the wrong function be being called? __strtok_r_1c sounds like a "1
character" function.
