[ODE] Lots of warnings when compiling version 0.039

[Frederic Ferland]

Just downloaded the new ODE version and I get a whole lot of warnings (see 
below) when I compile using VC++ 6.0.  Is that a known 'issue' and can 
these warnings be safely ignored?  Any chance this could be cleaned up in 
the CVS repository?  I like always prefer my builds to be warning free... :)

warning C4291
------------------------
  no matching operator delete found; memory will not be
  freed if initialization throws an exception
   d:\libraries\ode\objects.h(48) : see declaration of 'new'

warning C4244
------------------------
  'initializing' : conversion from 'double' to 'float', possible loss of data

warning C4800
------------------------
  'int' : forcing value to bool 'true' or 'false' (performance warning)

warning C4305
------------------------
  'initializing' : truncation from 'const double' to 'const float'


Thanks!
