The reason can also be including <R.h> (as done in simecol) that includes <math.h>

Do I understand it correctly that this means that including <R.h> is wrong in C++?
I read "Writing R extensions" several times, but was not aware that this was a mistake. If I replace <R.h> by <cmath> then it works on my systems, but I want to be certain that there are no other side effects.

Thanks in advance for clarification!
