Thanks for the responses. I am building on 64-bit Linux. I rebuilt azone2 as a 32-bit application and it runs fine.

And most importantly, the mobs in Moors follow the terrain now.

For any Fedora folks out there, you'll need:
zlib-devel-1.2.5-6.fc16.i686

I looked into building a working 64-bit version. There is some sort of sizing error, as the following is 20 bytes long rather than 12. Probably alignment.

struct struct_header {
  unsigned long offset;
  char magicCookie[4];
  unsigned long unknown;
} typedef struct_header;

PS: Reading the structure field-by-field may be the easiest solution
