I ran into problems when trying to select *many* files at once with
wxFileDialog. I'm using version 2.8.9 on 32bit windows. The 'File name:'
input field is limited to a length of 2^15 characters. Is it possible to
change this? I had a look at the source but it seems none of it is
actually used because wxUSE_FILEDLG isn't set.
