+- wxLogXXX() are now macros, not functions. Because of this calling them with
+  an explicit scope resolution operator ("::wxLogError()") doesn't work any
+  longer, just remove it. Also notice that using them inside an "if" statement
+  without enclosing parentheses results in warnings from g++ with -Wparentheses,
+  add parentheses around the if statement body to work around it.
