1997-05-21 17:50 Ulrich Drepper <drepper@cygnus.com> * elf/Makefile (dl-routines): Add dl-sysdepio. * elf/dl-support.c (_dl_sysdep_fatal): Removed. * sysdeps/generic/dl-sysdep.c: Move definition of _dl_sysdep_fatal, _dl_sysdep_error and _dl_sysdep_warning to ... * sysdeps/generic/dl-sysdepio.c: ...here. * sysdeps/mach/hurd/dl-sysdep.c: Move the functions to ... * sysdeps/mach/hurd/dl-sysdepio.c: ...here. * sysdeps/unix/sysv/linux/powerpc/dl-sysdep.c: Remove definition of functions. Bug reported by Marcus G. Daniels <marcus@cathcart.sysc.pdx.edu>. * db/Makefile (libdb.so): Depend on libc.so for dynamic loading and for Linux ld.so. * login/Makefile (libutil.so): Likewise. * math/Makefile (libm.so): Likewise. * md5-crypt/Makefile (libcrypt.so): Likewise. * nis/Makefile (libnss_%.so): Likewise. * resolv/Makefile (libnss_dns.so): Likewise. 1997-05-20 14:01 Miles Bader <miles@gnu.ai.mit.edu> * argp-help.c (_help): Supply STATE to argp_args_usage. (argp_args_usage): Add filtering of the args doc string. (comma): Print cluster headers for the first entry too. * argp.h (ARGP_KEY_HELP_ARGS_DOC): New macro. Patches by Jean-François Bignolles <bignolle@ecoledoc.ibp.fr>. Include <config.h> if HAVE_CONFIG_H is defined. * sunrpc/xdr_float.c: Likewise.
