I tried the attached strtod.c but it converts 4.9406564584124654418e-324
to 0.0 setting errno to 34(ERANGE).  So I am afraid it is not usable
for libraries/clib/native/Double.c.

$ cat DoubleTest.c
#include <stdlib.h>
#include "strtod.c"
extern int errno;

int main(int argc, char* argv[]) {
   double d = strtod(argv[1], NULL);
   printf("%s %d %40.20e\n",argv[1], errno, d);
}

$ cc -o DoubleTest DoubleTest.c -lm
