 ANSI build too

 - Virtual wxHtmlParser::AddText() takes wxString, not wxChar*, argument now.
 
-- Funtions that took wxChar* arguments that could by NULL in wxWidgets 2.8.
+- Functions that took wxChar* arguments that could by NULL in wxWidgets 2.8.
   are deprecated and passing NULL to them won't compile anymore, wxEmptyString

+- wxTmemxxx() functions take either wxChar* or char*, not void*: use memxxx()

 - Removed insecure wxGets() and wxTmpnam() functions.
 
 - Removed global GetLine() function from wx/protocol/protocol.h, use
