the above two lines should be after all other includes.  that's the style for
X_messages.cc, since it avoids compile errors.  In this case,
speech_input_result.h is already included by speech_input_messages.h, so you can
take it out from here (if it wasn't included in the header, you'd get a compile
error if this wasn't before #IPC_MESSAGE_IMPL)

Removed speech_input_result.h as suggested
