Header-only Boost.System

Hi All,

In my application, I'm trying to use Boost ASIO via boost 1.66 and defining the following two macros in the Makefile. Basically trying to use the header-only approach. 

CFLAGS += \
-DBOOST_ERROR_CODE_HEADER_ONLY \
-DBOOST_SYSTEM_NO_DEPRECATED
But then I came across this thread: https://lists.boost.org/Archives/boost/2017/10/239106.php 
"In header only mode, multiple instances may appear and thus no
longer be proper singletons. Stuff breaks in this situation, badly."
Is the above applicable to 1.66 too?How can I safely use the header-only approach in boost 1.66?

Thanks,Ashish
