* hurd/hurdinit.c (map0): Remove [!PIC] conditional.cvs/libc-960616
* shlib-versions (*-*-*): Add libutil=1. * rpm/Makefile (install-lib): Add libc.a et al. (install-others): Only add libc.so if $(build-shared) is yes. * math/Makefile (install-lib): New variable, list libieee.a. (non-lib.a): Likewise. (extra-objs): Likewise, and ieee-math.o. ($(objpfx)libieee.a): New target, link to ieee-math.o. * math/ieee-math.c: New file. * sysdeps/unix/sysv/linux/Makefile [$(subdir)=math]: Remove setfpucw and libieee.a stuff. * sysdeps/unix/sysv/linux/ieee-fpucw.c: File removed. * sysdeps/unix/sysv/linux/i386/ieee_fpu.c: File removed.
