No longer able to compile w/GNU python

I'm using:

OS:  Linux 4.16.14-300.fc28.x86_64 #1 SMP Tue Jun 5 16:23:44 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux (Fedora 28)

Python: Python 2.7.15 (default, May 16 2018, 17:50:09)
[GCC 8.1.1 20180502 (Red Hat 8.1.1-1)] on linux2

icc: Intel(R) C Intel(R) 64 Compiler for applications running on Intel(R) 64, Version 18.0.3.222 Build 20180410

Not so long ago, I was perfectly able to compile C functions which called python modules, using GNU python.  Here's an example:

#include <Python.h>
#include <complex.h>

double complex c2f1_mpmath_cp_ca(double complex a1, double complex a2, double complex b1, double complex z)
{
/* local variables declarations */
   int npars= 4;
   double complex result;
   PyObject *pName, *pModule, *pFunc, *pArgs, *pValue;
   PyObject *pa1, *pa2, *pb1, *pz;
   Py_complex res_pc;

   if(! Py_IsInitialized()) Py_Initialize();
   pa1= PyComplex_FromDoubles(creal(a1),cimag(a1)); 
   pa2= PyComplex_FromDoubles(creal(a2),cimag(a2));
   pb1= PyComplex_FromDoubles(creal(b1),cimag(b1));
   pz=  PyComplex_FromDoubles(creal(z),cimag(z));

   pName = PyString_FromString("mpmath");
   pModule = PyImport_Import(pName);
   pFunc = PyObject_GetAttrString(pModule, "hyp2f1");
   pArgs = PyTuple_Pack(npars, pa1, pa2, pb1, pz);
   pValue = PyObject_CallObject(pFunc, pArgs);
   res_pc= PyComplex_AsCComplex(pValue);
   result= res_pc.real + res_pc.imag*I;
   return result;
}

Now, all of a sudden, a lot of errors appear.  Any idea what could be causing the errors below?
