Thanks.  Several other people have reported the same thing.  We know how
to fix it - it's a case of expanding the symbol table built into the
dynamic linker, but what I don't know is under what conditions we should
do this (i.e. what configure tests do we need to add).  I really need to
get my hands on a box that displays the bug.

The boxes I have access to all have __umoddi3 in libc (as well as
libgcc, presumably).  Perhaps it wouldn't do any harm to always add
these symbols to the Linker's symbol table (on Linux, at least).

Cheers,
