HP nm still dumps core even with weak turned off.  However, HP `nm -p'
seems to work ok.  GNU nm is confused about symbol types and possibly
its scope, printing `?' for most symbols in objects generated by g++.
I think it is the `-ffunction-sections' and `-fdata-sections' options
used in building libstdc++ that is confusing GNU nm.  This is probably
also the cause of HP nm dumping core without `-p'.  My guess is this
is also giving the linker problems.
