[ODE] still having problems building under vs.net 2002 (vs7.0)

[Mike Reinstein]

Russ:

I tried changing them from extern inline to static but it didnt solve the 
problem
I think I have a vague idea of whats going on
take the following excerpt from odemath.h:

#ifdef __cplusplus
static float dDISTANCE (const float a[3], const float b[3])
	{ return (float) dSqrt( (a[0]-b[0])*(a[0]-b[0]) + (a[1]-b[1])*(a[1]-b[1]) + 
(a[2]-b[2])*(a[2]-b[2]) ); }
static  double dDISTANCE (const double a[3], const double b[3])
	{ return dSqrt( (a[0]-b[0])*(a[0]-b[0]) + (a[1]-b[1])*(a[1]-b[1]) + 
(a[2]-b[2])*(a[2]-b[2]) ); }
#else
...
#endif

when I attempt to compile my project, trhe first error I encounter in 
odeMath.h is at the 2nd declaration of dDistance. Here the error:
odemath.h(148): error C2733: second C linkage of overloaded function 
'dDISTANCE' not allowed

it seems to me as though its not able to differentiate between float and 
double types, and is subsequently not able to overload the ddistance 
function because  static  double dDISTANCE(...) and static float 
dDISTANCE(...) collide


any thoughts?
