+Subject: [PATCH] m4: MSVC defines __cplusplus as 199711L still
+
+See e.g.
+<https://stackoverflow.com/questions/37503029/cplusplus-is-equal-to-199711-in-msvc-does-it-support-c11>,
+on MSVC we can't depend on the value of __cplusplus, since that one is a
+too low value, even if everything else works fine.
