A recent change to suffix.hpp seems to cause several tests to fail when 
compiling with Oracle Developer Studio12.5.

The error is:
  "CC" -std=c++11  -xO4 -mt -erroff=%none -m32 -DBOOST_ALL_NO_LIB=1 
-DBOOST_CHRONO_STATIC_LINK=1 -DBOOST_SYSTEM_NO_DEPRECATED 
-DBOOST_SYSTEM_STATIC_LINK=1 -DBOOST_TEST_NO_AUTO_LINK=1 
-DBOOST_TIMER_STATIC_LINK=1 -DNDEBUG -D__typeof__=__typeof__ -I".." -c 
-o ./count.o" "../libs/accumulators/test/count.cpp"

"../boost/config/suffix.hpp", line 628: Error: Badly formed constant 
expression.
