["Markus F.X.J. Oberhumer" <markus.oberhumer@jk.uni-linz.ac.at>] Bug#38311: <string.h> is not -Wconversion warning free

[Andreas Jaeger]

This tiny program gets some warnings from <bits/string2.h> if compiled 
with -Wconversion:
#include <string.h>

int main(void)
{
  return 0;
}

$ gcc -Wconversion -Werror tst.c -O2
cc1: warnings being treated as errors
/usr/include/bits/string2.h: In function `__strsep_g':

                 from tst.c:1:

I don't understand the warning at the moment.  Anybody else with a
fix?
