[Qt-interest] libgcc_s_dw2-1.dll License Question

Hi,

since Qt 4.5 Nokia releases Qt among others under LGPL.
So if a software is released conform to the LGPL restrictions, the
software itself can be proprietary.
Since Qt 4.6 mingw was update to version 4.4 which depends on libgcc
(libgcc_s_dw2-1.dll) on windows.
As the mingw runtime is public domain, the dependency on "mingw10.dll"
is ok.
But I'm not sure about the libgcc_s_dw2-1.dll . I see it's GLP with the
"GCC Runtime Library Exception".
May I distribute this dll with Qt 4.6 and a proprietary application? Or
do I have to recompile Qt with static libgcc.

Thanks a lot for your help/clarification.
Chris
