Build is broken on Windows

[jacquelinekay]

The ROS 2 buildfarm is failing to build FastRTPS on Windows right now.

Console output from a set of branches that do not change FastRTPS can be found here (from ~1 hour ago): http://ci.ros2.org/job/ci_windows/1192/console#console-section-6

The problem seems to be:

16:10:32 C:\Program Files (x86)\Microsoft Visual Studio 14.0\VC\include\xtree(2075): error C3848: expression having type 'const eprosima::fastrtps::rtps::ChangeForReaderCmp' would lose some const-volatile qualifiers in order to call 'bool eprosima::fastrtps::rtps::ChangeForReaderCmp::operator ()(const eprosima::fastrtps::rtps::ChangeForReader_t &,const eprosima::fastrtps::rtps::ChangeForReader_t &)' [C:\J\workspace\ci_windows\ws\build\fastrtps\src\cpp\fastrtps.vcxproj]

I reproduced this on my Windows 10 VM.

It's not a blocker for us right now because we can disable any of our supported middlewares on CI, however it prevents us from testing ROS 2 code built with FastRTPS for all platforms.

thank you :)
