I built libg++ version 2.2 on a HP 9000/730 (running HP-UX 8.05)
using GCC version 2.2.2.  Whenever I try to link libg++.a with
any C++ program, no matter how trivial, I always get the following
error from the linker:

ld: Unsatisfied symbols:
   _vt.filebuf (data)


For example, here's what happens when I try to install libg++-2.2:
-----------------------------------------------
...
        cd test-install; make test-90S  \
            CC=/usr/local/bin/gcc COMPILE_FLAGS="" LIBS=-lg++
        ./foo_main.run > foo_main.out
        diff ./expected.out foo_main.out >foo_main.diff
        /usr/local/bin/gcc   -c a.cc
        /usr/local/bin/gcc -o a  a.o -lg++
ld: Unsatisfied symbols:
   _vt.filebuf (data)
collect: /bin/ld returned 1 exit status
*** Error code 1
 
Stop.
*** Error code 1
 
Stop.
*** Error code 1
 
Stop.
-----------------------------------------------

What is the cause of this error?
