COMP: getting rid of MSVS warning

Warning read:
  'conversion' conversion from 'type1' to 'type2', possible loss of data
caused by using std::copy in ITK.

This is solved by including itkWin32Header.h before everything else.

OMP: remove gcc compiler warnings

Warning read:
  warning: format %<x> expects argument of type <type1>, but argument 3 has type <type2>

  Solved by using C++'s ostringstream instead of C's sprintf.
