He's probably having the same problems I had when this change was made.  I
can't remember exactly what I did to get around it, but I think it involved
manually installing the interface files for the new version of the library
so they were used by the old compiler when compiling the new one.

This was not the case in this instance; it was a single change that broke
the compiler.  Thus you could either hack your way around the problem, or
wait a few weeks for the next successful rotd build.  :-)

Needless to say, I'm glad you've come up with a simpler "upgrade" path for
Zoltan's changes than he had originally.  I suspect I may have ceased
keeping up with the development (now that it's not essential that I do so)
if I'd had to do that much mucking around.
