Make Scintilla build properly with GCC/MinGW 
Fix GCC compile error: extra qualification 'WordList::' on member 'SetWordAt' [-fpermissive]

Fix GCC compile error: a storage class can only be specified for objects and functions

Fix GCC compile error with invalid usage of conditional operator
  Invoke the "afterthought" part of the for loop in the normal code at the
  end of the loop where proper conditions can be used.
  Error message:
  third operand to the conditional operator is of type 'void', but the second operand
  is neither a throw-expression nor of type 'void'

closes #1656
closes #1655
