[linux-minidisc] compiling libnetmd and netmdcli on windows

[Thomas Arp <manner.moe@gmx.de>]

Hi, if found some incompatibilities when compiling on windows/mingw32.

1. libnetmd/common.c :  sleep() is not defined/implemented
I fixed this using windows Sleep() function by adding following lines to common.c

#ifdef WIN32 /* use windows internal Sleep() function */

    #include <windows.h>

    #define sleep(x) Sleep(x)

#endif

2. libnetmd/utils.h and utils.c :  "int min(int a,int b)" is already defined in windows.h
I fixed this by defining NOMINMAX to not use the windows function.
I just added following line to libnetmd.pro and netmdcli.pro

win32:DEFINES += NOMINMAX

3. libnetmd/utils.h :  missind definition of ETIMEDOUT in errno.h
I fixed this by defining it.

#ifdef WIN32 /* add missing definitions for errno on windows */

    #define ETIMEDOUT 70 // Operation timed out

#endif

4. libnetmd/secure.c and netmdcli/netmdcli.c :  ramdom() is not defined and implemented
I fixed this as a "bloody hack" in utils.h using
#ifdef WIN32

    #include <stdlib.h>

    #include <time.h>

    static int random(){srand(time(NULL));return rand();};

#endif

But i think it´s better to use a rondom number generating function which is available on all platforms, maybe use one from libgcrypt.

I´ll send a patch later after we have discussed the random() problem.
