[Debian-med-packaging] Bug#739184: ray: FTBFS on mips/mipsel/s390x: error: 'memcpy' was not declared in this scope

[Aurelien Jarno]

Package: ray
Version: 2.3.0-1
Severity: serious
Tags: upstream patch
Justification: fails to build from source (but built successfully in the past)

ray fails to build from source on mips, mipsel and s390x with the
following error:

|   CXX RayPlatform/actors/Actor.o
| RayPlatform/actors/Actor.cpp: In member function 'void Actor::send(int, Message*)':
| RayPlatform/actors/Actor.cpp:54:52: error: 'memcpy' was not declared in this scope
|    memcpy(newBuffer, oldBuffer, bytes * sizeof(char))

I still do not understand why it builds fine on other architectures,
but in C++, memcpy is declared in <cstring>. The following patch
therefore fixes the issue:
