Hello,

This, cleans up one part of a long dangling thread.  Per:
http://sources.redhat.com/ml/gdb-patches/2003-11/msg00462.html
This modifies the unwind code so that it uses the test:

+      && get_frame_func (this_frame) == entry_point_address ()

that that in place, the old inside_entry_func can be made static to 
blockframe.c.  This should reduce Kevin's patch to just doco + frame.c 
tweaks.

comments?
