I made some progress with the bridges code and also some bug fixed for linux
sparc gdb. Now I will cleanup but leave a trail by making all the bridges
related issues to be duplicates to this issue. Then a make a new isue for future
work.

I made some changes to bridges code and
now I get a stacktrace from inside the bridges. I need do some more editing then
i will commit some new code in a cws for reviewing and debugging. I wonder what
are the valid values for these? nFunctionIndex=0, nVtableOffset=-268446224
