[flac-dev] flac on windows 2000

[lvqcl]

If anybody wants to know: current flac.exe is not compatible with
Windows 2000. The only reason for this is the following line from
get_utf8_argv() function from src/share/win_utf8_io/win_utf8_io.c:

     if (wgetmainargs(&wargc, &wargv, &wenv, 1, &i) != 0) return 1;

Windows 2000 has slightly older version of msvcrt.dll, and this check
always fails. I found an explanation about it here:

(it's not something that should be fixed, of course)
