how to use wsprd.exe from WSJT-X with WSPR-X
(idea from IZ7SLZ)

replaced wsprd.exe
called wsprd from commandline

copied libgfortran-3.dll
copied libquadmath-0.dll
copied libwinpthread-1.dll
error: entry point "__addtf3" not found

copied libusb-1.0.dll
replaced libstdc++-6.dll
copied libgomp-1.dll
replaced libgcc_s_dw2-1.dll
replaced libfftw3f-3.dll

=> works with wspr-x v0.8 r3058
