Okay, I was thinking about this whole situation a bit yesterday and decided to
finish the patch I'm using and make it usable also for other people. The result
is in this bzr branch:

http://bzr.oxygene.sk/taglib/taglib.win32/

I'll try to keep it always in sync with the KDE SVN (for my own needs :)). If
you want to test the code without using bzr, here are patches against 1.4 and
SVN trunk (r549613):

http://users.musicbrainz.org/~luks/patches/taglib_r549613_win32.diff

What's changed:

 * All classes, static methods and functions from the C bindings are
   exported to DLL. There are two macros to control this:
    - TAGLIB_NODLL to disable DLL exports
    - TAGLIB_API_EXPORTS should be defined when building TagLib

 * File::File -- all file names on Windows are treated as UTF-8 by default.
   On NT-based systems are used "wide-char" IO functions, which means Unicode
   support for paths up to 32000 characters long. On Win 95, 98 and Me are used
   classic IO functions and ANSI codepage.

 * New functions File::useWinAnsiCP and taglib_file_use_ansi_cp to
   set whether you want to use ANSI CP rather than UTF-8 in file names.

As the Autotools build system from official tarballs is not in the SVN, I didn't
even try to port/test it. To use these patches you will need some win-compatible
build system. Here is an ugly SCons script I use:
