[minor bug] macro conflict for M_PI_2 and M_SQRT1_2 with math.h

When using the _USE_MATH_DEFINES preprocessor definition, the
#define M_SQRT1_2 7.0710678118654752440E-1
#define M_PI_2 1.5707963267948966192E0
definitions in Standard_math.hxx are conflicting with the same ones from math.h

Could you please enclose the definitions in Standard_math.hxx with #ifndef / #endif ?

#ifndef M_SQRT1_2
#define M_SQRT1_2 7.0710678118654752440E-1

#ifndef M_PI_2
#define M_PI_2 1.5707963267948966192E0

So if you are using the "free" version of OCC you have just helped them to fix a bug that will only be given to paying customers for now, you will not get it until the next "major" release, very logical.

The bug is still open in my revision 6.5.1.
Does the fix give trouble?
