Thanks for your reply Eli. Actually what I did about a half an hour after posting was reboot my PC. Then the compiler had no problems. So I am guessing the OS had some pending transactions that were settled with the reboot. Maybe that should be recommended in the notes about what to do after installation. I also found that I didn't have to explicitly declare the .exe for the output file. The GNU compiler/linker added it. Same thing with the -shared switch, the .dll extension is automatically suffixed.
