# Red Hat BZ:

#
# ChangeLog
#
#2013-04-30  Patsy Franklin  <pfrankli@redhat.com>
#
#	* iconv/gconv_cache.c (find_module): Demangle init_fct before 
#	checking for NULL. Mangle __btowc_fct if init_fct is non-NULL.
#	* iconv/gconv_db.c (free_derivation): Check that __shlib_handle 
#	is non-NULL before demangling the end_fct.  Check for NULL
#	end_fct after demangling.
#	(__gconv_release_step): Demangle the end_fct before checking 
#	it for NULL.   Remove assert on __shlibc_handle != NULL.
#	(gen_steps): Don't check btowc_fct for NULL before mangling.  
#	Demangle init_fct before checking for NULL.
#	(increment_counter): Likewise
#	* gconv_dl.c (__gconv_find_shlib): Don't check init_fct or
#	end_fct for NULL before mangling.
#	* wcsmbs/btowc.c (__btowc): Demangle btowc_fct before checking
#	for NULL.
