Thu Sep 5 03:20:42 1996 Ulrich Drepper <drepper@cygnus.com> Change configuration and Makefiles to allow add-ons to have a sysdeps/ directory hierachy. * configure.in: Test for sysdeps/ directory in add-ons.

(io): Move bus_memory_base and sparse_bus_memory_base into struct. (_hae_shift): New function. * sysdeps/unix/sysv/linux/alpha/sys/io.h: New file. Prototypes for the bus query functions. Sat Aug 31 18:14:54 1996 Richard Henderson <rth@tamu.edu> * elf/dl-close.c (_dl_close): In static executables, map->l_prev can be NULL when unloading a library. * elf/dl-open.c (_dl_open): Pass __environ instead of __libc_envp to the library .init function. * sysdeps/alpha/dl-machine.h (elf_machine_rela): Since we omitted part of the COPY reloc processing earlier, omit the rest now -- we'll get into less trouble later when some fool does use a COPY. * sysdeps/unix/sysv/linux/init-first.c (init): Accept argc et al as parameters.
