Update.

	* misc/syslog.c: Change to allow user the interpretation of the
	outcome even with syslog having no return value.

1998-02-05 20:41  Wolfram Gloger  <wmglo@dent.med.uni-muenchen.de>

	* elf/dl-addr.c: Fix search algorithms in dladdr(); don't assume
	that the number of program headers is >0 (which is wrong for the
	loader itself).
