* config.h.in (getenv): Don't test THIS_IS_YMAKEFILE to see if we
should exclude the getenv declaration; instead, test NOT_C_CODE.
Per suggestion from Francesco Potorti`.
* ymakefile (NOT_C_CODE): Define this; it's true, and useful.
* config.h.in (volatile): Don't define this to be the empty string
if some file has #defined HAVE_VOLATILE.
