Can you tell me what they are?

Hi, Richard,

I found this in gcc/ChangeLog:

Thu Feb 25 23:43:59 1999  Richard Henderson  <rth@cygnus.com>

	* Makefile.in (print-rtl.o): Depend on basic-block.h.
	(flow.o): Depend on tree.h and insn-flags.h.
	(sched.o): Depend on tree.h and expr.h.

But I couldn't find them in Makefile.in. I can see print-rtl.c include
basic-block.h and flow.c include insn-flags.h. But I cannot see anywhere
tree.h be included by flow.c and sched.c.

BTW, without dependencies on insn-flags.h and basic-block.h, the build
may fail. Missing insn-flags.h kills the parallel build on SMP at
random.

Thanks.
