Update.

1998-03-11 15:27  Ulrich Drepper  <drepper@cygnus.com>

	* elf/rtld.c: Update help message.
	Install link maps for preloaded objects using main_map as loader.

	* elf/dl-misc.c: Use __libc_write instead of __write for debugging.
	* elf/dl-profile.c: Likewise.

	* elf/dlsym.c: Little optimization.
	* elf/dlvsym.c: Likewise.

1998-03-11 14:56  Ulrich Drepper  <drepper@cygnus.com>

	* posix/wordexp-test.c: Move test for parameter list at the very
	beginning.

1998-03-11 00:16  Tim Waugh  <tim@cyberelk.demon.co.uk>

	* posix/wordexp.c (wordexp): Set we_wordc to zero initially unless
	WRDE_REUSE flag is set.
	(parse_param): Allow `*', `@', and numbers in parameter names.
	(parse_dollars): Differentiate between arithmetic expansion and a
	command substitution that starts immediately with a sub-shell
	(like ``$((1+3))'' as opposed to ``$((echo);(ls))'').
	(parse_param): Memory allocated with __alloca in a block was
	referenced outside that block.  Adjusted to use malloc/free.
	(parse_param): Adjusted field-splitting algorithm so that there is
	not necessarily a field split at the end of a parameter expansion.

1998-03-10 19:52  Tim Waugh  <tim@cyberelk.demon.co.uk>

	* posix/wordexp.c (wordexp): If about to return WRDE_NOSPACE,
	don't free words that have already been allocated.
	(parse_param): A dollar sign on its own will never have a pattern
	associated with it (like "${HOME%%/}" has), so don't try to free it.
	(parse_glob): Attempt to glob when an unquoted `[' is found
	(rather than an unquoted '{' (!)).  Also for unquoted '?'.
	(parse_glob): Sorted out quoting in a glob-able word.
	(parse_param): Added $* and $@ handling.
