I think we're talking past each other.  This patch is about
tv32-compat.h.  tv32-compat.h contains conversion functions between
e.g. struct timeval with 32-bit time_t and struct timeval with 64-bit
time_t.  I still don't see any reason why these conversion functions
need to be different on Alpha than they are on the 32-bit
architectures.

Alpha is unusual in that certain legacy code paths need to call these
conversion functions, but *what the functions do* should be identical
to what they do on 32-bit architectures.  There should be no need for
preprocessor magic or anything.
