gcc 4.3 correctly determines that input() is unused and gives the
following warning:
-- snip --
...
HOSTCC arch/powerpc/boot/dtc-src/dtc-lexer.lex.o
dtc-lexer.lex.c:1436: warning: ‘input’ defined but not used
...
-- snip --
Fix it by adding %option noinput to
arch/powerpc/boot/dtc-src/dtc-lexer.l and
regeneration of arch/powerpc/boot/dtc-src/dtc-lexer.lex.c_shipped.
