Please review this patch that configures C++ arguments on build jobs that involve compiling CPP files. As a result of this change, CPP files are compiled with `-std:c++14` command line argument instead of `-std:c11`, which is used when C++ arguments are not configured. While at it, I simplified the `java.security.jgss/Lib.gmk` file by moving the additional include directory to `EXTRA_HEADER_DIRS`.
This patch fixes the following clang warning: warning: argument unused during compilation: '-std:c11' Microsoft states that [std:c++14 is the default](https://learn.microsoft.com/en-us/cpp/build/reference/std-specify-language-standard-version?view=msvc-170), so there shouldn't be any differences in produced code. Testing: - verified that after the changes, all CPP files are compiled with `std:c++14` instead of `-std:c11` - spot-checked a few `cmdline` files that changed after this patch was applied; the `-std` change was the only difference - tier1-5 builds, tier1-2 tests and client libs tests continue to pass on Windows, Linux & MacOS. ------------- Commit messages: - Update copyright - Simplify makefile - Revert template changes - Use CXXFLAGS where CPP files are compiled Changes: https://git.openjdk.org/jdk/pull/14758/files Webrev: https://webrevs.openjdk.org/?repo=jdk&pr=14758&range=00 Issue: https://bugs.openjdk.org/browse/JDK-8311247 Stats: 22 lines in 5 files changed: 16 ins; 0 del; 6 mod Patch: https://git.openjdk.org/jdk/pull/14758.diff Fetch: git fetch https://git.openjdk.org/jdk.git pull/14758/head:pull/14758 PR: https://git.openjdk.org/jdk/pull/14758
