Help fixing a couple errors

[Edelweise]

This is a module (.dll) for an old game called Diablo II. It is compiling with Visual C++ 6.0, but I get the following errors while compiling:

I was trying to type down all the errors and explain each other, but I get totally lost there, so I will just post screens ( this is from Visual C++ 6.0 )

In every screen I will mark the error and show the code that cause it above in the editor.

I don't know why the IDE says there are 10 errors. I calculated 13, but anyway half of them are duplicates (same error, different line) so I guess these will be easy to fix.

2 error:

3 error (kinda same as the 1st one, totally lost there ...):
