g++/libg++ 1.36.1 difficulties

 recently i tried installing g++/libg++ 1.36.1.  g++ wasn't
 a problem.  libg++ also compiled just fine.  when i try to test
 libg++ ('make tests') i get complaints about undefined symbols.

 the symbols are ___CTOR_LIST__ and ___DTOR_LIST__.  these are 
 defined in gnulib3.c (libg++/src) as externs.  after searching for
 the actual declarations, i see that the loader somehow secretly
 knows about these symbols... i think.

 when i define NO_GNULIB3 and rebuild libg++.a from scratch, i get
 complaints about ___main being undefined.

 has anyone ever seen this before?  how do i fix this?

 also...  the HINTS file in the g++ distribution states that as of
 1.36, g++ does not automatically link in libg++, yet g++ (or ld++)
 complains about not finding libg++.a (when libg++.a isn't installed).
 so i can't use g++ until libg++ (or whatever...) is fixed.

 if it matters, this is on a Sun3 running SunOs 4.0.3.

 down below is the output from 'make tests'...

 thanks!,
 chris

 ps: also, forgive me if this one has been addressed already.  we were off
     the 'usenet' air for a brief while and consequently lost some news...
