Hi gurus,
I intend to dive into mysterious XS field. But my first try failed.;( Below is head and C files. 
test.h

#define TESTVAL      3 
 extern int      max(int, int); 


test.c

#include "./test.h"
 int max(int a, int b) 
 { 
 return ((a>b)? a:b); 
 }

I ran 4 steps as perldoc h2xs: All things look fine, but when I run dmake, it throws error: 
C:\Mytest>perl Makefile.PL
