Subject: R-alpha: Probably <float.h> instead of <values.h> for an automatic .Machine

I checked with some ANSI gurus here are work and we can't see that
either <values.h> or <float.h> are required by the ANSI standard.
However, <float.h> is required by the POSIX standard and it appears to
define pretty well everything that is needed in the .Machine object
except (naturally) for the maximum integer and other values based on
the integer representation.
