 From the README:

    This is version 0.92 of the unwind library.  At the moment, only the
    IA-64 Linux (IPF Linux) platform is fully supported.  Some very basic
    support for x86 exists also.  However, the x86 support is based purely
    on the frame-chain and does not use unwind information, so its utility
    is limited.

Don't know how useful that would be, but it seems like if this is the 
right kind of tool, the x86 support could either be extended as much as 
is neccessary to handle exceptions or the algorithms could be looked at 
and lifted out...
