* Makerules: Define build-module-asneeded.
* iconvdata/extra-module.mk: Use build-module-asneeded. needed. 2006-01-09 Richard Henderson <rth@redhat.com> * iconvdata/extra-module.mk ($(objpfx)$(mod).so): Depend on ld.so. * sysdeps/alpha/__longjmp.S: Use PTR_DEMANGLE. * sysdeps/alpha/setjmp.S: Likewise. Avoid __sigjmp_save for rtld; tailcall in libc.so. * sysdeps/unix/sysv/linux/alpha/sysdep.h (PTR_MANGLE): Define. (PTR_MANGLE2): Define. 2006-01-11 Ulrich Drepper <drepper@redhat.com>
