we weren't actually using these sources anymore, okay?

-
-// File:
-//   This file define a macro that allows the creation of or emulation of C++17
-//   inline variables based on whether or not the feature is supported.
-
-////////////////////////////////////////////////////////////////////////////////
-// Macro: ABSL_INTERNAL_INLINE_CONSTEXPR(type, name, init)
-//
-// Description:
-//   Expands to the equivalent of an inline constexpr instance of the specified
-//   `type` and `name`, initialized to the value `init`. If the compiler being
-//   used is detected as supporting actual inline variables as a language
-//   feature, then the macro expands to an actual inline variable definition.
-//
-// Requires:
-//   `type` is a type that is usable in an extern variable declaration.
-//
-// Requires: `name` is a valid identifier
-//
-// Requires:
-//   `init` is an expression that can be used in the following definition:
-//     constexpr type name = init;
-//
-// Usage:
-//
-//   // Equivalent to: `inline constexpr size_t variant_npos = -1;`
-//   ABSL_INTERNAL_INLINE_CONSTEXPR(size_t, variant_npos, -1);
-//
-// Differences in implementation:
-//   For a direct, language-level inline variable, decltype(name) will be the
-//   type that was specified along with const qualification, whereas for
-//   emulated inline variables, decltype(name) may be different (in practice
-//   it will likely be a reference type).

-#ifdef __cpp_inline_variables
-
-// Clang's -Wmissing-variable-declarations option erroneously warned that
-// inline constexpr objects need to be pre-declared. This has now been fixed,
-// but we will need to support this workaround for people building with older
-// versions of clang.
-//
-// Bug: https://bugs.llvm.org/show_bug.cgi?id=35862

-// Note:
-//   identity_t is used here so that the const and name are in the
