But of course they are. Thou shalt use off_t and ifdef it for Solaris 2.6
Suppose you have:
fstat(fd, &inode)
printf("%d\n", inode.st_size);
st_size is off_t (64 bits), but %d wants int (32 bits, the same as long).
Thou shalt use "%dll" and guard it with ifdef from normal systems.
And if not... Imagine all those HTTP servers returning "Content-Length: 0".
Now, if you don't put that define, everything works. Or not? :)
