Trying to understand the Angband 3.X source code

[nppangband]

This weekend I began the project of trying to update the NPP source code with as much of the Andi Sidwell era development as possible (NPP is currently based on Angband 3.0.6, the last RR version).

My first attempt is to get the stores to interact like they do in the current Angband. I didn't get very far. I incorporated most of the updates in store.c, but my compiler (lcc-win32) gives more than a screenful errors for the display related functions, like this one:

static void store_display_entry(menu_type *menu, int oid, bool cursor, int row, int col, int width)

I added the ui-event.c and ui-menu.c to the build, along with the helper files listed in store.c, and now I get pagefuls of compile errors from those files instead. I am clearly missing a major section of code that need to be worked into my project, but I can't tell what it is. Is there anyone out there who can give me any guidance on this? Thanks.
