The .align directive used to align storage locations is ambiguous. On some platforms and assemblers it takes a byte count, on others the argument is interpreted as a shift value. The current usage expects the first interpretation. Replace it with the unambiguous .balign directive which always expects a byte count, regardless of platform and assembler.
