Checking back on this, I realize that the example I gave does not match the description; the example should be as follows:
#include <gsl/gsl_sf.h>
#include <stdio.h>
#include <gsl/gsl_math.h>
int main (void){
double out;
out = gsl_sf_hyperg_1F1_int(0, 1, GSL_NAN);
printf("%f\n", out);
printf("%.21e\n", out);
return 0;
}
