-frepo and missing symbols on FreeBSD

[bryan at yahoo-inc dot com (bryan d. o'connor)]

i'm having problems with template instantiation when i am compiling
a rather large multi-file program that uses STL.  to get around the
multiple definitions of free_list, etc.. i started using the template
repository (-frepo).  it fixed the problem with multiple defs but now
i'm getting undefined symbols for some things.

i narrowed it down to a small test case:
  FreeBSD 2.1.7.1
  gcc version egcs-2.90.23 980102 (egcs-1.0.1 release)

sample program:

  #include <map>

  #ifndef REPO
  template less<int>;
  template map<int, int, less<int> >;
  #endif

  main() {
    map<int, int, less<int> > foo;
  }

> egcs++ -c foo.cc                      # explicitly instantiating..
> egcs++ -o foo foo.o

works.  (and actually, in this case, not explicitly instantiating
does work also -- but it breaks for the multi-file case.)

> egcs++ -frepo -DREPO -c foo.cc        # using the repository.. 
> egcs++ -frepo -o foo foo.o
foo.o: Undefined symbol `rb_tree<int, pair<int const, int>, select1st<pair<int const, int> >, less<int>, __default_alloc_template<false, 0> >::__erase(__rb_tree_node<pair<int const, int> > *)' referenced from text segment
collect2: ld returned 1 exit status

looking at foo.rpo, i do see an entry for this symbol:
O __erase__t7rb_tree5ZiZt4pair2ZCiZiZt9select1st1Zt4pair2ZCiZiZt4less1ZiZt24__default_alloc_template2b0i0Pt14__rb_tree_node1Zt4pair2ZCiZi


any suggestions?  thanks!
