Background: we have in sc/source/filter/inc/ftools.hxx supposedly
"safe" casts that are (according to the Doxygen documentation)

they are actually so buggy as to be *less* safe.
Back in November, I wrote a prototype _actually_ safe versions, but
got sidetracked and forgot about them. I'm unearthing them again now,
attached.
It might be a little orthogonal to just the cast issue, but I wonder if
Cert's IntegerLib or SafeInt (http://safeint.codeplex.com/) or somesuch
(https://bugzilla.mozilla.org/show_bug.cgi?id=555798) covers the same
ground and is license-suitable as a drop in ?
