As Linus hasn't put it into i386 (nor Alpha), he has
some good reason. Ask him for guidance.

Mainly I think we should NEVER use slow 64/* division routines
in fast paths.

Case of ADFS (and Apple HFS, and quite a many others) is that
they don't support file sizes exceeding 32 bits, do they ?

In such environments, VFS i_size (and loff_t *ppos) are
extra large for what is needed, and before doing block size
divisions, you can safely cast the value to (long).

As an end-result you will get your system free of need for
libgcc.a, and possible dangers lurking in it.
