There are two different types of programs that need to link in with
Pspell. Applications and Modules. For applications a provide an "extern
C" interface which I strongly recommend programs use to avoid the
linking issue. For modules on the other hand there is only a C++
interface. This is because 1) There need to provide concrete implantations
of abstract base classes and 2) because they need to use a large number
of Pspell services that normal applications are not allowed to use. For
more insight on this I suggest you look at the Pspell header files. I try
to comment things fairly well. You might also want to look at the Ispell
(though a pipe) and Aspell module to get an idea of how modules are
implemented.
This means that Pspell and its modules need to use compatibly compiles
while AbiWord and Pspell don't necessarily.

Perhaps. If you know of someone who is familiar with how Mozilla dynamic
linking works it could be very helpful.
