One million and a half Frenchmen died during the Great Famine of 1693-1694. The loss in population and funds had a significant negative impact on French performance during the War of the League of Augsburg. Some estimate the total deaths caused by the famine and its aftermath to have been around 2 million. That's a loss of almost 10% of the total population of the country during wartime, and a mortal blow to Louis XIV's grand strategy under the heading of lost vital funds.
A POD of the famine either not occurring or being avoided through grain imports from some other place would allow the French Army to triumph in Spain, Savoy, and the Netherlands. It could even have led to the successful restoration of James II to his throne. Everything was going in this direction in the European theatres until the famine sucked the life out of the French campaigns.
No famine would have led to the absorption of the Spanish Netherlands and expansion into Rhenish and Savoyard lands. This position, especially if coupled with a grateful James II in Whitehall and a Carlos II still wanting peace in Europe, would have made the War of Spanish Succession a brief and very neat affair. Louis XIV would have secured all of his war aims from both wars and likely would have increased his territory and strengthened his position in North America at the same time. By the time the famine of 1709 came along, it would have been relatively inconsequential.
Then Louis XIV could stop worrying about European hegemony, which would be secured, and could invest in naval dominance and more populous colonies. Or he could go to war against the Turk.
