+	* g-socthi-mingw.ads, g-socthi-vms.ads: Remove C_Read and C_Write from
+	internal implementation unit GNAT.Sockets.Thin,
+	as their usage for sockets is non-portable (using the read and write
+	functions from the system runtime library is fine on UNIX but won't
+	work under Windows).
+
+	* mingw32.h: Update copyright notice.
