Subject: VC6 compilation fixes for wxTreeListCtrl.
X-Git-Url: https://git.saurik.com/wxWidgets.git/commitdiff_plain/276f3938c4ae6420a05ad2a7667fdf79261c33d6

VC6 compilation fixes for wxTreeListCtrl.

For some reason comparing wxTreeListItem with its associated Type doesn't work
when using VC6 ("error C2593: 'operator ==' is ambiguous") so help the compiler
to do it.

Also remove the unnecessary (and unsupported by VC6) return from void function.
