No, I'm, getting the same error.

What I did was to #include <ode/config.h> in gim_math.h and replace the 
#define of GREAL float
#if defined(dSINGLE)
typedef float GREAL;
#elif defined(dDOUBLE)
typedef double GREAL;
#error You must #define dSINGLE or dDOUBLE

as it is done in include/ode/common.h

Then at 2 place you have to change float to GREAL and everything compile 

I will create a patch for that soon.

The problem I see now it vec3f can be a double and the "f" can be 
Should the name change completely to use dVector3 (which is really an 
array of 4)
or have Gimpact have its own gVec3 ??
