    gio_w = g_io_channel_new_file( "iochannel-test-outfile", "w", &gerr);

/**
 * g_io_channel_new_file:
 * @filename: A string containing the name of a file.
 * @mode: One of "r", "w", "a", "r+", "w+", "a+". These have
 *        the same meaning as in fopen().
 * @error: A location to return an error of type %G_IO_FILE_ERROR.
 *
    `w'
          Open the file for writing only.  If the file already exists,
          it is truncated to zero length.  Otherwise a new file is
          created.

(This is the GNU libc definition, but I'm sure it corresponds
to the ISO standard)

So, probably some fix is needed in your g_io_channel_new_file()...
since the code looks like the Unix version, it may be that
the Win32 implementation of open() is buggy in its handling
of 
       flags = O_WRONLY | O_TRUNC | O_CREAT;

But I"m not really in a position to suggestion an alternate way
of doing things or a workaround.
