* Rules (subdir_install): Depend on $(common-objpfx)sor-$(subdir). [! libc.so-version]: Clear static-only-routines. ($(common-objpfx)sor-$(subdir)): New target. [static-only-routines]: New static pattern rule for these .so's. * Makerules [libc.so-version] ($(slibdir)/libc.so): Target removed. [libc.so-version] ($(libdir)/libc.so, $(common-objpfx)libc-syms.so): New targets replace it. (install) [libc.so-version]: Depend on $(libdir)/libc.so instead of $(slibdir)/libc.so. * io/Makefile (static-only-routines): New variable. * configure.in: Check for tools objdump and objcopy, and for awk. * config.make.in (OBJDUMP, OBJCOPY, AWK): New variables. Thu May 9 01:24:00 1996 Ulrich Drepper <drepper@cygnus.com> * locale/programs/config.h: Remove definition of wint_t. * locale/programs/ld-collate.c: Include <wchar.h> instead of <wcstr.h>. * manual/time.texi: Add some more description for %U and %W format of strftime. Describe new format %V of strftime. * resolv/gethnamaddr.c: Prevent warning by preventing variable definition. * stdio-common/_itoa.c: Ditto.
