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

[Andreas Jaeger <aj@arthur.rhein-neckar.de>]

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':
In file included from /usr/include/string.h:346,
                 from tst.c:1:
/usr/include/bits/string2.h:1091: warning: passing arg 2 of `__strpbrk_c2' with different width due to prototype
/usr/include/bits/string2.h:1091: warning: passing arg 3 of `__strpbrk_c2' with different width due to prototype

/usr/include/bits/string2.h:1091: warning: passing arg 4 of `__strpbrk_c3' with different width due to prototype

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

Andreas

P.S. The report comes from Debian.

Package: libc6-dev
Version: 2.1.1-6

libc6 2.1 breaks program which are compiled with "-O2 -Wconversion -Werror"
because <string.h>  is not warning free any longer.

The #define of strpbrk in line ~890 in /usr/include/bits/string2.h
is causing one of those warnings.

Probably an upstream problem.
