Squish some warnings

[Neil Booth <neil at daikokuya dot demon dot co dot uk>]

These were easy to squash.  Others would confuse the logic, so I've
left them untouched.

Bootstrapped and made check x86 Linux.  OK to commit for mainline?

Neil.

	* dwarfout.c (dwarfout_init): Add cast.
	* sched-deps.c (sched_analyze_insn): Remove unused vars.
	* unwind-dw2-fde.c (_Unwind_Find_FDE): Flag unused parameter so.
cp:
	* method.c (build_mangled_C99_name): Remove unused prototype.
