* strftime.c (strftime):
Handle E and O modifiers, required for POSIX.2 and XPG4.
Don't use sprintf to format numbers; this way, we can handle time_t
correctly regardless of whether it's signed.
Don't dump core if format ends in %.
In default %c format, use %e instead of %d, for POSIX.2 compatibility.
For %z:
Use tm_gmtoff if available.
Output nothing if tm_isdst is negative.
Output correct value even if arg is 1969-12-31 23:59:59 UTC.
Don't assume that UTC offset is less than 24 hours;
Posix requires support for 24 hours, and there's no point
limiting it at all.

Rewrite description of %V to match ISO 8601.
Fix TZ Posix string example for US Eastern time.
Explain tzname[1] when DST isn't used.

Explain that timezone's sign is opposite from tm_gmtoff, and that
timezone lacks DST adjustment whereas tm_gmtoff has it.
Deprecate tzname and timezone.

from drepper.

done in _dl_relocate_object.

(routines, elide-routines.so): Add dl-support.
* elf/dl-minimal.c (_dl_pagesize): Remove common defn.
* elf/dl-load.c (_dl_pagesize): Define it here.
(_dl_map_object_from_fd): Initialize it if zero.
* elf/link.h (_dl_pagesize): Remove const.
Sun Jun 9 04:04:26 1996 Roland McGrath <roland@delasyd.gnu.ai.mit.edu>
* elf/Makefile (routines): Add dl-symbol.
* elf/dl-lookup.c (_dl_symbol_value): Moved to ...
* elf/dl-symbol.c: New file.
* elf/elf.h (Elf32_Xword, Elf32_Sxword): New types.
(Elf32_Section, Elf64_Section): New types, 16 bits.
(Elf32_Sym, Elf64_Sym): Use it.
* elf/dl-deps.c (_dl_open): Moved to ...
* elf/dl-open.c: New file.
* Makefile (routines): Add dl-open.
* elf/Makefile (dl-routines): New variable.
(routines): Add $(dl-routines).
(elide-routines.so): New variable, set to $(dl-routines).
(libdl-inhibit-o): Variable removed; build all flavors of -ldl.
(rtld-routines): All but rtld, dl-sysdep, and dl-minimal moved to
$(dl-routines).
* elf/dl-lookup.c (_dl_lookup_symbol): Remove magic symbol grokage.
* elf/dladdr.c: Use ELFW(ST_BIND) in place of ELF32_ST_BIND.
* elf/dl-load.c (open_path): Use __ names for open and close. Avoid
using strdup.
(_dl_map_object): Likewise.
(_dl_map_object_from_fd): Use __ names for mmap, munmap, and mprotect.
* elf/dl-minimal.c (malloc): Likewise.
* elf/dl-reloc.c (_dl_relocate_object): Likewise.
* elf/dl-minimal.c (_dl_pagesize): New variable.
(malloc): Use that instead of a static variable.
* elf/dl-reloc.c (_dl_relocate_object): Use _dl_pagesize instead of
calling getpagesize.
* elf/dl-load.c (_dl_map_object_from_fd): Likewise.
* elf/link.h: Declare _dl_pagesize.
* elf/rtld.c (dl_r_debug): Renamed to _dl_r_debug.
* elf/link.h (struct link_map): Use Half for l_phnum instead of Word.

(_dl_sysdep_start): Update prototype of DL_MAIN function ptr arg.
* elf/dl-load.c (_dl_map_object_from_fd): Use explicit Elf32_Word to
extract 4-byte magic number, not ElfW(Word). Match EI_CLASS against
native wordsize, either 32 or 64.
* elf/elf.h (Elf64_Byte, Elf64_Section): Typedefs removed. In C a
char is always a byte, no need for a typedef. Section indices are
16-bit quantities in elf64, which already have a typedef Elf64_Half.
Remove partial -lelf implementation. There is now a
separately-distributed `libelf' package that implements it.
* elf/dl-lookup.c: Don't #include <libelf.h> any more.
(_dl_elf_hash): New function, moved from
libelf.h:elf_hash.

* elf/Makefile (headers): Remove libelf.h.
(extra-libs): Remove libelf.
(libelf-routines): Variable removed.
* elf/Makefile (libdl.so): Remove commands from this target. The
implicit rule commands are correct, this explicit rule just serves to
add some dependencies.
* elf/dl-lookup.c (_dl_lookup_symbol): Use ELFW(ST_TYPE) in place of
ELF32_ST_TYPE. Likewise ST_BIND.
* elf/do-rel.h (elf_dynamic_do_rel): Likewise R_SYM.
* elf/link.h (ElfW): New macro for wordsize-independent ElfXX_* type
naming.
(ELFW): New macro, likewise for ELFXX_* macro naming.
(_ElfW, _ElfW_1): New macros, subroutines of ElfW and ELF.
Sat Jun 8 20:52:38 1996 Roland McGrath <roland@delasyd.gnu.ai.mit.edu>
* elf/link.h, elf/do-rel.h, elf/dynamic-link.h, elf/dl-deps.c,

elf/dl-runtime.c, elf/dladdr.c, elf/dlclose.c, elf/dlsym.c,
elf/linux-compat.c, elf/rtld.c: Change all uses of `Elf32_XXX' to
`ElfW(XXX)' for wordsize-independence.
Sat Jun 8 20:50:42 1996 Richard Henderson <rth@tamu.edu>
* elf/elf.h: Move Elf64_* types in parity with Elf32 counterparts.
