This seems to have been observed up to GCC 3.1 at least in XEmacs
code.

Don't weight that information too heavily, though, as Emacs has
historically implemented what should be a C union of several types
(including pointers) with mask-and-cast operations on integers.  So
it's hard to say whether it's our own unclean implementation or a real
GCC bug.
