link problem

[J dot Freyh at gmx dot de]

Hi all,

I build a new gcc, g++ along with latest snapshot of libstdc++-2.90.8.
Build
and installation went well. But when I compile the simple program you see
below I get some undefined references during link.

--------------------------------
The Program:

#include <iostream>
using namespace std;
main()
{
cout << "Hello" << endl;
exit(0);
}
---------------------------------

Command line and errors:
c++ -v -fhonor-std -o proc proc.cpp

--------------------------------------------------------
It seems the problems is locatated in the libgcc.a because:

> nm --demangle libgcc.a | grep "std::exception"
produces empty output

but 

> nm --demangle libgcc.a | grep exception0000062c t find_exception_handler

What went wrong.

I would appreciate some hints

Thanks
