  • inst/include/absl/hash/internal/hash.h
  • inst/include/absl/meta/internal/constexpr_testing.h

abseil 2023.8.2.2

• Package is now compiled (NeedsCompilation: yes).
• The configure script (Unix/macOS) and configure.win (Windows) compile all 153 production Abseil source files in inst/include/absl/ into a static library libabsl.a, which is installed into the package's libs/ directory.
• Added abseil_lib() R function that returns the path to the installed libabsl.a, allowing downstream packages to link non-header-only Abseil components without recompiling the library themselves.
