Hi,

This is expected behaviour. The mingw{32,64}-pthreads package only
contain shared libraries at the moment so even if you specify the
'-static' compiler flag it will still create a dependency on the
pthreads dll.

You might want to look into the possibility of adding support for a
static pthreads library to the mingw-pthreads package and creating a
mingw{32,64}-pthreads-static subpackages.

Kind regards,
