However, the changes doc mentions it (and a DumpPEF showed it), FetchFontInfo() is exported by both the InterfaceLib and the FontManager (stub) libraries. Although the FontManager lib is only available for OS 9.0 and higher, maybe it's necessary to link against it?

I think you need to weak-link against the library.  If you do this, then
the system will not complain if the library is missing, but if you do call
the function something bad happens.  But if you make sure not to call the
function unless the library is present, you're fine.  It's common for an
application to weak-link against NavigationLib, for example, and if it's
missing to use the Standard File package instead.

Also, can everybody please hard-wrap the lines of your messages?
