euler87.c: Funktionen mit static definieren

Browse source 
Beim Kompilieren mit clang -Weverything hat sich gezeigt, dass der
Compiler eigentlich gern eine Deklaration der Funktionen zuvor hätte. Um
dem Compiler zu sagen, dass diese Funktionen nur innerhalb dieser
Compilie-Unit benötigt werden und daher keine Deklaration zuvor notwendig
ist, müssen die Funktionen mit static versehen werden.
