Problems with running make-mingwlibs

Hi,

I am trying to build the Krypton branch on Windows 10 64 bit.

When I run make make-mingwlibs then libdvdnav, libdvdread and libdvdcss file to down load.

I can see that a line like :- wget –tries=5 –retry-connrefused –waitretry=2 –no-check-certificate -c https://github.com/xbmc/libdvdcss/master.tar.gz -O libdvdcss-master.tar.gz is being exeuted (which seems o.k. to me) but I end up with libdvdcss-master.tar.gz being a zero length file and the following error :-

–2017-02-12 12:29:59– https://github.com/xbmc/libdvdcss/master.tar.gz

Can anybody be of any help ?
