In C++, a function declaration with an empty parameter list means that the function takes no arguments. In C, however, it means that the function takes an unspecified number of parameters. What we did previously was therefore non-conforming. This caused a config check to fail in the curl port, as it was able to redeclare `rand` as taking an int parameter.
