CXXSTD was added as the C++ analogue to CSTD. CXXSTD defaults to `-std=c++11` with supporting compilers; `-std=gnu++98`, otherwise for older versions of g++. This change standardizes the CXXSTD variable, originally added to googletest.test.inc.mk as part of r345203. As part of this effort, convert all `CXXFLAGS+= -std=*` calls to use `CXXSTD`. Notes: This value is not sanity checked in bsd.sys.mk, however, given the two most used C++ compilers on FreeBSD (clang++ and g++) support both modes, it is likely to work with both toolchains. This method will be refined in the future to support more variants of C++, as not all versions of clang++ and g++ (for instance) support C++14, C++17, etc. Any manual appending of `-std=*` to `CXXFLAGS` should be replaced with CXXSTD. Example: Before this commit: ``` CXXFLAGS+= -std=c++14 ``` After this commit: ``` CXXSTD= c++14 ``` Reviewed by: asomers Approved by: emaste (mentor) MFC after: 1 month MFC with: r345203, r345704, r345705 Relnotes: yes Tested with: make tinderbox Differential Revision: https://reviews.freebsd.org/D19732
