Sure! If KDE apps are compiled without the -D_FILE_OFFSET_BITS=64 and
-D_LARGEFILE64_SOURCE flags, KDE apps will not be able to correctly
pass variables of type off_t to libraries that are compiled with those
flags, such as libsmbclient. For example, if kio_smb is not compiled
with -D_FILE_OFFSET_BITS=64 and -D_LARGEFILE64_SOURCE, the smbc_lseek
function moves the cursor to a different position than was requested.
