// The following inclusion of <cstdio> prior to "ppl_c_test.h" is to
// work around a bug whereby some versions of <stdio.h> do not obey
// clause D.5.2 of the C++ standard: "Each C header, whose name has
// the form name.h, behaves as if each name placed in the Standard
// library namespace by the corresponding cname header is also placed
// within the namespace scope of the namespace std and is followed by
// an explicit using-declaration (7.3.3)."  By including <cstdio>
// prior to "ppl_c_test.h" we ensure std::FILE is defined at the time
// when "ppl_c.h" will include <gmp.h>.
