Hi
Thanks for you help.

Yes , thats what I meant :

warning: auto-importing has been activated without --enable-auto-import 
specified on the command line.
This should work unless it involves constant data structures referencing 
symbols from auto-imported DLLs.Info: resolving vtable for 
boost::unit_test::unit_test_log_tby linking to 
__imp___ZTVN5boost9unit_test15unit_test_log_tE (auto-import)

Is this really normal ?
And is it really good ? I once had exactly the same sort of warning ( 
compiling stuff not related to boost ) and it turned out
that I linked against a dll with Visual C++ Symbols ( that were not 
exported in a way that gcc can handle them correctly ).
The resulting executable was basically undefined behavior.

In any case, I do not want to live with compiler/linker warnings.
Usually, as far as I know, on windows ( and also on cygwin on windows ) 
the standard way would be to create a .dll and then use that to create 
an import library .lib that is linked against. The .dll itself is not 
required for the linking process.

Am I missing something ? Is there a way to use shared libs in Boost.Test 
without linker warnings ( that I know from experience have to be taken 
very seriously in this particular case ) ?

Again, thanks for help
