[Dwarf-discuss] New libdwarf/dwarfdump

[David Anderson]

A new libdwarf and dwarfdump is on 
	http://reality.sgiweb.org/davea/

The following routines are new in libdwarf.h.
See the libdwarf postscript for details.


The dealloc calls enable complete and correct dealloc, and are simper
to use than pre-existing dealloc.

 .debug_pubtypes support is new.

With a one-line change you can build a fully-checking libdwarf
for testing/debugging your client code (see libdwarf/malloc_check.h
and libdwarf/malloc_check.c for details).
