Note that they (pread, etc.) would better not exist at all instead of being stubbed out (this requirement was dropped, AFAICS).

You usually do the opposite, emulate utimes with utime ;) link_warning(utimes, "the use of LEGACY `utimes' is discouraged, use `utime'") -- To unsubscribe from this list: send the line "unsubscribe linux-embedded" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
