error in template code

[Emmanuel]

A compilation error appears while compiling a custom plugin which uses otherwise unused template code.

The error message is:
stellarium-0.12.0/src/core/VecMath.hpp:698:50: erreur: no match for ‘operator-=’ in ‘((Vector4<double>*)this)->Vector4<double>::v[3] -= (& a)->Vector4<T>::operator/<double>(((Vector4<double>*)this)->Vector4<double>::v[3])’

This can be traced back to a typo in VecMath.hpp file:
 691 template<class T> void Vector4<T>::operator+=(const Vector4<T>& a)
 692 {
 693 v[0] += a.v[0]; v[1] += a.v[1]; v[2] += a.v[2]; v[3] += a.v[3];
 694 }
 695
 696 template<class T> void Vector4<T>::operator-=(const Vector4<T>& a)
 697 {
 698 v[0] -= a.v[0]; v[1] -= a.v[1]; v[2] -= a.v[2]; v[3] -= a/v[3];
 699 }
 700

At line 698 there is a "/" instead of a "." in the computation of v[3].
