Update.

1998-09-01 15:36  Ulrich Drepper  <drepper@cygnus.com>

	* malloc/Makefile: Include Makeconfig before testing config-sysdirs.

	* malloc/mtrace.c: Add bug report address.  Update email address.
	Add more @XXX@ to print correct address size.

	* elf/dl-addr.c (_dl_addr): Make sure that map to be examined is
	really initialized.

	* elf/dl-close.c (_dl_close): Use l_map_start and l_map_end info
	for munmap call instead of examining phdr again.
	Free all malloc()ed strings and arrays.
