	* 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.
