[PATCH] S390: Fix build error in iconvdata/bug-iconv11.c


I get the following build error on S390 31bit while building the test iconvdata/bug-iconv11.c with gcc 5.3: gcc bug-iconv11.c -c -std=gnu11 -fgnu89-inline -O3 -Wall -Werror -Wundef -Wwrite-strings -fmerge-all-constants -frounding-math -Wstrict-prototypes -Wold-style-definition -mlong-double-128 -I../include -I/home/stli/glibcDir/glibc-20160119_31-build/iconvdata -I/home/stli/glibcDir/glibc-20160119_31-build -I../sysdeps/unix/sysv/linux/s390/s390-32 -I../sysdeps/unix/sysv/linux/s390/fpu -I../sysdeps/s390/fpu -I../sysdeps/unix/sysv/linux/s390 -I../sysdeps/s390/nptl -I../sysdeps/ieee754/ldbl-64-128 -I../sysdeps/ieee754/ldbl-opt -I../sysdeps/unix/sysv/linux/include -I../sysdeps/unix/sysv/linux -I../sysdeps/nptl -I../sysdeps/pthread -I../sysdeps/gnu -I../sysdeps/unix/inet -I../sysdeps/unix/sysv -I../sysdeps/unix -I../sysdeps/posix -I../sysdeps/s390/s390-32/multiarch -I../sysdeps/s390/s390-32 -I../sysdeps/wordsize-32 -I../sysdeps/s390/multiarch -I../sysdeps/s390 -I../sysdeps/ieee754/ldbl-128 -I../sysdeps/ieee754/dbl-64 -I../sysdeps/ieee754/flt-32 -I../sysdeps/ieee754 -I../sysdeps/generic -I.. -I../libio -I. -D_LIBC_REENTRANT -include /home/stli/glibcDir/glibc-20160119_31-build/libc-modules.h -DMODULE_NAME=nonlib -include ../include/libc-symbols.h -o /home/stli/glibcDir/glibc-20160119_31-build/iconvdata/bug-iconv11.o -MD -MP -MF /home/stli/glibcDir/glibc-20160119_31-build/iconvdata/bug-iconv11.o.dt -MT /home/stli/glibcDir/glibc-20160119_31-build/iconvdata/bug-iconv11.o
bug-iconv11.c: In function âtest_ibm93xâ:
bug-iconv11.c:59:11: error: format â%tdâ expects argument of type âptrdiff_tâ, but argument 2 has type âsize_t {aka long unsigned int}â [-Werror=format=]
   printf ("  ==> %td: %s\n"
cc1: all warnings being treated as errors

This patch uses %zu format specifier for argument size_t ret instead of %td.

Ok to commit?



	* iconvdata/bug-iconv11.c (test_ibm93x):
	Use %zu printf format specifier for size_t argument.
