- wxCHECK family of macros now must be followed by a semicolon
- wxMBConv::cMB2WC() and cWC2MB() take size of the input buffer and return
length of the converted string in all cases now.
- wxHtmlWindow::OnCellClicked() now returns bool.
- wxHtmlCell::OnMouseClick() was deprecated and replaced with
wxHtmlCell::ProcessMouseClick(); old code overriding OnMouseClick() will
continue to work with WXWIN_COMPATIBILITY_2_6, but should be rewritten to
use ProcessMouseClick().
