[PATCH] SH: Fix compile time warnings

[Kaz Kojima]

Hi,

Mainline fails to bootstrap for sh4-unknown-linux-gnu because of
a few warnings in compiling sh.c.

../../LOCAL/gcc/gcc/config/sh/sh.c:269: warning: 'sh_adjust_unroll_max' declared 'static' but never defined
../../LOCAL/gcc/gcc/config/sh/sh.c:7557:27: error: C++ style comments are not allowed in ISO C90
../../LOCAL/gcc/gcc/config/sh/sh.c:7557:27: error: (this will be reported only once per input file)
cc1: warnings being treated as errors
../../LOCAL/gcc/gcc/config/sh/sh.c: In function 'ua_offset':
../../LOCAL/gcc/gcc/config/sh/sh.c:8772: warning: old-style function definition

I've accidentally set --disable-werror when testing sh-elf-4_1 branch
and missed these warnings.  The patch below fixes it.  Ok for mainline?

Regards,
	kaz

	* config/sh/sh.c: Declare the prototype of sh_adjust_unroll_max
	only when TARGET_ADJUST_UNROLL_MAX is defined.
	(general_movsrc_operand): Use the C style comment.
	(ua_offset): Use prototype.
