1998-02-17  Andreas Schwab  <schwab@issan.informatik.uni-dortmund.de>

	* elf/dl-load.c (add_name_to_object): Don't translate strings.
	* elf/dl-minimal.c (_strerror_internal): Define it here to avoid
	pulling in the whole error list.
	(__dcgettext, dcgettext): Removed.
	* libc.map: Export _strerror_internal.

1998-02-18 10:50  Ulrich Drepper  <drepper@cygnus.com>

	* sysdeps/i386/fpu/t_exp.c: New file.

1998-02-18  Andreas Jaeger  <aj@arthur.rhein-neckar.de>

	* nis/libnss_nisplus.map: NIS+ support is new in glibc 2.1, add
	everything with version GLIBC_2.1.
	* hesiod/libnss_hesiod.map: Likewise.

1998-02-18  Andreas Jaeger  <aj@arthur.rhein-neckar.de>

	* manual/arith.texi (Old-style number conversion): This node is a
	section, not a subsection.

1998-02-17  Andreas Schwab  <schwab@issan.informatik.uni-dortmund.de>

	* elf/dl-lookup.c (make_string): Use __stpcpy instead of stpcpy.

1998-02-17  Andreas Schwab  <schwab@issan.informatik.uni-dortmund.de>

	* elf/rtld.c (dl_main): Make sure that the library search paths
	have been initialized before the first call to _dl_map_object.

1998-02-17  Andreas Schwab  <schwab@issan.informatik.uni-dortmund.de>

	* Makerules (common-generated): Add libc_pic.os.

1998-02-17  Andreas Schwab  <schwab@issan.informatik.uni-dortmund.de>

	* elf/rtld.c (dl_main): Use PT_PHDR to figure out the load address
	of the executable.
