[MPlayer-cygwin] MultiByteToWideChar et al.

[Ulf-Dietrich Braumann]

Hello,

I am trying to build version mplayer 1.4 (as well as a source snapshot as of 
Oct 25, 2021) on a well administered cygwin installation

%uname -a CYGWIN_NT-10.0 XXXX-XX-XXX 3.2.0(0.340/5/3) 2021-03-29 08:42 x86_64 
Cygwin

however, I end up with some weird codepage trouble:

Some ideas how to solve? Last time when I was building mplayer 1.3 I did not 
have such problems.
