Shared library annoyance with gcc-3_0-branch

[Richard Kenner]

    But we can't just move exception handling to a language-specific
    library, because we are attempting to support cross-language exception
    mechanisms (for example, C++ and Ada).

Right, but that doesn't mean it has to be in libgcc.  I would be happier
if libgcc were just the basic support routines in libgcc[12].c and if
the exception routines (because they have been problematic) were moved
into a new library, say libgcceh.
