I have revisited my earlier working version of MinGW and run the MinGW installer to see what upgrades were proposed. These were upgrades 5.31 to 5.32 of: mingw32-mingwrt (dev and dll) mingw32-w32api (dev) It appears that after upgrading my above program now ceases to compile. I think I will now revert to the earlier version until I hear of further upgrades.
