w53_32_c() and w97_32_c() are defined as stubs when snow encoder is
disabled.  In this case, those functions are not referenced at all
and do thus not need to be defined.

These casts are correct and safe.  The pointers are guaranteed to
have proper alignment, and aliasing is not a problem with character
types.

The presence of the .SECONDARY directive caused thing to not always

Force version.sh to run whenever the version might have changed,
regardless of what is being built.  This is done by attaching the
dependencies to a dummy file (.version) which is included from the
makefile.  As make will always attempt to rebuild any included files
before considering other rules, this ensures that the real version.h
is (re-)created before it is required by any source file.

Changing directory is better than moving the file afterwards.
