No problem. However, I will do this tomorrow when anoncvs is in sync:
I forgot to comment out the typeof() compiler check (which will fail
for SUN Forte) in configure.ac for libsigc++-1.9.9 and just committed
the change ...


By the way, gcc-3.3 obviously has a compiler bug that prevents the
compilation of the adaptor bind test case:

test_bind.cc: In function `int main()':
test_bind.cc:63: error: ambiguous class template instantiation for 
`struct
   sigc::bind_functor<1, int, foo>::deduce_result_type<int, void, 
void, void,
   void, void, void>'
../sigc++/adaptors/bind.h:144: error: candidates are: struct
   sigc::bind_functor<1, T_bound, T_functor>::

../sigc++/adaptors/bind.h:141: error:                 struct

../sigc++/adaptors/bind.h:138: error:                 struct

and so on. The last partial template specialization listed in
the error message is the only one the compiler should consider
and both gcc-3.2 and gcc-3.3.2 work correctly. I removed some
unnecessary template specializations in cvs so that now, only
bind<0>() doesn't compile with gcc-3.3.


The True64 compiler on the other hand is a laugh:

cxx  -I. -I. -I.. -I..    -g -c -o test_deduce_result_type.o `test -f 
'test_deduce_result_type.cc' || echo './'`test_deduce_result_type.cc
cxx: Error: test_deduce_result_type.cc, line 15: namespace "std" has no
          member "cout"
{ std::cout << "int" << std::endl; }
-------^

and so on. There are some other errors that seem to be solvable
but I am not motivated to change back to "using namespace std"
in the examples to make this compiler happy!
