Update.

2003-09-27  Wolfram Gloger  <wg@malloc.de>

	* malloc/malloc.c: Include <malloc-machine.h> earlier instead of
	"thread-m.h", so that default parameters can be overridden in a
	system-specific malloc-machine.h.  Remove extra ; from extern "C"
	closing brace.
	* sysdeps/generic/malloc-machine.h: New file.
	* sysdeps/mach/hurd/malloc-machine.h: New file.
	* malloc/thread-m.h: Removed.
	* malloc/Makefile: Remove CFLAGS-malloc.c parameter addition, it
	is in sysdeps/generic/malloc-machine.h now.

	* elf/dl-reloc.c (_dl_allocate_static_tls): Move definition of
	variables only used if TLS_TCB_AT_TP is defined into the #if
	branch.
