2000-11-20 Jakub Jelinek <jakub@redhat.com> * iconvdata/bug-iconv2.c (main): Use %zd in format string. * io/test-lfs.c (do_test): Cast statbuf.st_size to long long. * malloc/tst-valloc.c (main): Cast valloc return value to long. * malloc/tst-obstack.c (verbose_malloc): Use %zd in format string. * math/test-fpucw.c (main): Use %lx in format string, cast control words to long. * stdio-common/tst-fmemopen.c (main): Use %td in format strings. * stdlib/tst-strtol.c (tests): Avoid (bogus?) decimal constant is so large that it is unsigned warning. * sysdeps/unix/sysv/linux/sparc/bits/types.h (__ssize_t): Changing it to long on sparc64. 2000-11-20 Andreas Jaeger <aj@suse.de> * nscd/nscd.h (termination_handler): Add noreturn attribute. (receiv_print_stats): Likewise. * elf/ldconfig.c (path_hwcap): Cast -1 for proper comparison.
