[lto] Bootstrap failure with your patch

[Diego Novillo]

Doug, your latest WPA patch fails to bootstrap because of:

/home/dnovillo/perf/sbox/lto/local.x86_64/src/gcc/lto-section-out.c:
In function 'produce_asm_for_decls':
/home/dnovillo/perf/sbox/lto/local.x86_64/src/gcc/lto-section-out.c:1183:
error: unused parameter 'set'

I've marked the argument with ATTRIBUTE_UNUSED, because I suppose that
at some point you'll want to emit decls on that set only?


Thanks.  Diego.
