Bugzilla Bug 87644

<math.h> included instead of <cmath> in vector.cxx

Reproducible: Always
Steps to Reproduce:
1. compile
2. won't compile
3.

Actual Results:  
vector.cxx: In member function `float CL_Vector::angle(const CL_Vector&) const':
vector.cxx:69: error: `acos' is not a member of `std'
vector.cxx: In member function `CL_Vector CL_Vector::rotate(float, const
CL_Vector&) const':
vector.cxx:90: error: `sin' is not a member of `std'
vector.cxx:91: error: `cos' is not a member of `std'
make[2]: *** [vector.o] Error 1
make[2]: *** Waiting for unfinished jobs....
make[2]: Leaving directory `/var/tmp/portage/construo-0.2.2/work/construo-0.2.2'
make[1]: *** [all-recursive] Error 1
make[1]: Leaving directory `/var/tmp/portage/construo-0.2.2/work/construo-0.2.2'
make: *** [all] Error 2 

Expected Results:  
compile

fixing #include <math.h> to #include <cmath> in vector.cxx made manual compile
possible.

output from emerge --info please?
