Okay. I restored the .h file and kept the mod in the cpp file. I tried building with that
setup.
Results were the same --- a failed build after about 20 minutes. I don't know if that
result will change by moving to a virtual machine environment with 3.5.10 not installed.
I will try that next!
I'll keep testing as my schedule allows the next few days but I know I won't be
able to provide much attention thereafter for a few weeks. I should be able to putter and
tinker a little bit during that time, so any bugs we resolve now will help much the next
few weeks.
