Have you finally tried this compilation becouse of me ? ;-)

I have solved this other way. I have added switch to patches.h include
#define AVOID_NAME_COLLISION_PATCH
and I will catch there all possible collisions with different compilators.
Then I used in sources when needed
#ifdef AVOID_NAME_COLLISION_PATCH
  POV_BLOB
#else
  BLOB
#endif

I have changed it the same way. This is the same case as BLOB collision.
'rad2' is constant in one of MinGW files. Check MinGW includes for it.

For example there is no make included in latest MinGW 2.0 packages. Some
strange ommision reported on MinGW website.
