🚀 go-pugleaf

I'm trying to compile Interviews 3.1-beta3 on a DECstation 5000/240 using
gcc/g++. I have only two errors that are preventing me from getting things
compiled. I'm afraid that my lack of experience with C++ is shooting me
in the foot.... At any rate, here are the two errors that I am getting.
Can anyone suggest how I can eliminate them?

Error #1:

Thanks for any help you can provide!
