Some, yes.  Sometimes fixes for one platform break another.  As a real
example, Rinternals.h was causing two C++-based compilers to object.
I changed a couple of declarations to a form that Metrowerks was known to
accept, and it passed on four others.  Then Luke found HP-UX's C compiler
objected, and had to change it again.

I really don't know how much independent evidence Debian's different
architectures provides, but my guess is that no else will be able to check
a 64-bit Linux.

Does that inform a cost-benefit analysis for you?
