A simple assignment would just copy (as is)
the improper 32-bit integer value
(passed in by the C program) into p
By performing a computation, it creates
a proper Euphoria atom, i.e. it creates an 8-byte
floating-point number to store the 32-bit integer value.

This trick can work because the translator does
not optimize-away additions by 0.0, nor does it
type-check parameter values.
(Note: I still haven't fully-tested this stuff.
I'm hoping the two interested people will try it.)
