Consider the following example taken from QTCREATORBUG-1175. The values lalala, lululu and lilili are not colored in purple, and are not shown in autocomplete.

Moving the enum declaration outside the function resolves this.

int main(int argc, char* argv[])
{
    enum Status { lalala, lululu, lilili };
    Status status = lalala;
    printf("%d", status);
}
