problem in mangling 'extern "java"' function in libjava

["Jeff Sparkes" <jsparkes at internetivity dot com>]

I'm compiling from CVS (yesterday specifically, but it's been happening for
a while)
on Debian Linux i386.  I'm compiling gcj, with libjava.  I've been getting
the following abort from prims.cc.  I've added a debug_tree just before the
abort to get more info.

It seems that the mangler doesn't handle types declared in extern "java".  I
certainly don't know how to handle it, but I'm sure someone does.
