These 2 macros are defined in os.h which cannot be included because it would reintroduce parts of {fmt} into the TU with different linkage and/or mangling. Avoiding such problems is the whole point of the PR. Unfortunately, pieces of the library are used in the implementation of the test support facilities of the library itself.

Let's use EOF instead of -1 here.
… rather than from the non-modular library which is baked into the `test-main` library. This averts linker problems: - strong ownership model: missing linker symbols - weak ownership model: duplicate linker symbols Simplify `gtest-extra.cc` while at it.
