mingw32-make: *** [gcc_mswd\medialib_mediactrl_am.o] Error 1
---------------------

The code cause error is :
        dVolume *= 1 - pow(10.0, -5.0);

If I change it to the following, it can be compiled ok :
        double tmp = 10.0;
        dVolume *= 1 - pow(tmp, -5.0);

the source code is from wxWidgets-2.8.8/src/msw/mediactrl_am.cpp

the gcc is from svn trunk 2008-08-14, build with mingw-w64.
