	The build error log

  http://releng.netbsd.org/builds/HEAD/200609140000Z/mmeye.build.failed

	contains the following messages (interspersed with ld.so warnings):

  insn-emit.c: In function 'gen_mshfhi_l_di':
  insn-emit.c:5476: warning: integer constant is too large for 'long' type
  insn-emit.c: In function 'gen_mshflo_l_di':
  insn-emit.c:5493: warning: this decimal constant is unsigned only in ISO C90
  --- insn-emit.o ---
  *** [insn-emit.o] Error code 1
  1 error

	This comes from the following constructs in the generated
	insn-emit.c file:

/* /u/build/HEAD/src/gnu/dist/gcc4/gcc/config/sh/sh.md:12273 */
rtx
gen_mshfhi_l_di (rtx operand0 ATTRIBUTE_UNUSED,

        const_int_rtx[MAX_SAVED_CONST_INT + (32)]),
        gen_rtx_AND (DImode,
        operand2,
        GEN_INT (-4294967296LL))));
}

        operand1,
        GEN_INT (4294967295LL)),
        gen_rtx_ASHIFT (DImode,

}

	(cut+pasted from my local i386 build host)

	I've admittedly not reproduced this build problem myself,
	I do not yet have an amd64 host set up for builds.  However,
	the ld.so warnings in the log is an indication that this was
	run on an amd64 host, at least...

>How-To-Repeat:
	Try to build -current mmeye from an amd64 -current host.

>Fix:
	Sorry, don't know.
