And no, samba team does not "request" all architectures to declare -DFILE_OFFSET_BITS. It is the setting with which samba is built (in order to support files >2Gb in size), - including libsmbclient too. So all functions in there which deal with file sizes and offsets - the one using off_t datatype - even on 32bit platforms like i386, use 64-bit value there. This is called LFS (Large File Support). When you compile your program without this #define on a 32bit system, you'll be getting off_t size = 4 bytes (32bits), but actual functions in actual libsmbclient are using prototypes with 64-bit off_t. So you'll be having weird runtime errors with everything seemingly correct.
I forgot to mention. The value for -DFILE_OFFSET_BITS &Co to use for a given system is obtained from the following command: getconf LFS_CFLAGS or as variable assignment: CFLAGS=$(getconf LFS_CFLAGS) /mjt
