# Additional config for C++11 support in R 3.6.
# R 3.6 no longer sets CXX11 flags without a full C++11 compiler present, but
# R 3.6.0 no longer sets CXX11 flags without a full C++11 compiler present, but
# the default gcc 4.4.7 still partially supports C++11 through -std=gnu++0x.
# Use the same CXX11 flags as the defaults in R versions prior to 3.6.0.
