	returns.
	* sysdeps/libm-ieee754/e_gammaf_r.c: Likewise.
	* sysdeps/libm-ieee754/e_gammal_r.c: Likewise.

	* include/dlfcn.h: Prototype them.  Prototype _dl_addr.
	* elf/Makefile (routines): Add dl-libc.c.
	* elf/dl-profstub.c (_dl_mcount_wrapper): Change type of
	argument to void *.
	* elf/ldsodefs.h: Change proto and use of _dl_mcount_wrapper to match.

	* iconv/gconv.c: Include dlfcn.h.
	* iconv/gconv_db.c: Likewise.
	* malloc/mtrace.c: Likewise.  Don't include ldsodefs.h.

	`handle' to a void *.
	(__gconv_find_func): Delete prototype.

	* iconv/gconv_dl.c: Don't include ldsodefs.h.  Remove
	dlerror_run and related functions and structs.  Use
