Well, for a start you'd have an older, more strong-willed and morally minded monarch on the French throne during Robert Turgot's attempts at free-market reform on French Wheat supplies. Louis XVI (This one) wouldn't have likely allowed such changes even if Turgot had managed to get into office without being able to leverage the influence of his friends close to OTL's Louis XVI. While that doesn't change the fact France is still... well, broke and suffering form poor harvests during the late 18th century, having the Monarchy continue to stabilize the price of bread in the cities and towns would go a long way to keeping the good graces of the urban working class that would eventually develop into the sans-culottes become the front line forces of governmental change during the French Revolution. An eventual Revolution would probably still emerge anyway; as radical changes and a calling of the Estates General would still be needed to get France back on solid financial footing, but it would likely have a far sharper rural/urban divide. The Middle Class, instead of identifying downward with the peasants, would likely identify upwards to those nobility favorable to constitutional reform and dedicated to dismantling Louis XIV's absolutism , facing off against a strong Catholic clergy (Who the pious Louis XVI would use as a power base) and their rural parishes who'd be on the short end of their stick as their feudal dues wracked up and farmers found it difficult to stay afloat as the monarchy forced them to sell their crops for much less than they're worth to keep the urban classes placated.
Alot however depends on what kind of political stances Louis develops once he gets a taste of governing. That could butterfly off in any number of directions, and we'd need a clearer idea of what he did during the 9 years between his historic death and his ascendance to the throne.
