You can't, it's not supported (yet), but what you want is the Wine
plugin API (http://wiki.winehq.org/WinePluginApi).

At the moment you have 2 options:
* Make a Windows application instead of a Linux application.
* Make a winelib application which will require wine to run but can
access Linux libraries as well (with some restrictions, eg. you have
to use Windows synchronization primitives instead of the pthreads
ones).

#include <windows.h>

int main(int argc, char **argv)
{
     HANDLE h;
     void (/*WINAPI?*/ *sort)(unsigned int,int);
     unsigned int *nums = malloc(sizeof(unsigned int) * 4);
     nums[0] = 3;
     nums[1] = 2;
     nums[2] = 1;
     nums[3] = 0;
     h = LoadLibrary("Arithmetic.dll");
     sort = GetProcAddress(h, "sort");
     sort(nums, 4);
}

winegcc main.c -o main
./main

MPlayer's code is GPL, so if you use it your code will be GPL too.
