I expect exe to be linked statically, but helper to be linked shared.
So 'a' uses 'helper' as a shared library.
My problem is this:
exe a : a.cpp helper1 helper2 : <link>static ;
lib helper1 : helper1.cpp ;
lib helper2 : helper2.cpp helper1 : <link>shared ;
When building 'a', I expect helper1 to be built only as shared. 'a'
statically and helper2 shared.
But what really happens is that helper2 is both compiled statically
*and* shared. Which leads to problems when singletons are used in
helper1 creates more than one singleton, at least in win32 DLL's
versus static library.
