Enumerating all affected types and grepping the headers installed by all
development packages in a distribution (documenting the details of what
was done, so distributors can repeat it for other distributions) - not
just those installed on a particular system - would seem a reasonable
approach.

The lack of a 64-bit version of some of glibc's own interfaces would seem
to be a fairly critical issue with any change to the default; before
changing the default, either a 64-bit version of those interfaces would
need adding, or those interfaces would all need to be made into compat
symbols for existing binaries only and the header removed.
