LPT.cpp and PoKeys55.cpp never imported the modules holding WriteLog,
ToLower and contains. Neither file is compiled on Linux, so nothing had
caught it; Console.cpp, which is built the same way, already had its
imports.
eu07.rc.in was stored in CP1250 - the o-acute in "pojazdow" is a single
0xF3 byte. rc.exe guessed a codepage, llvm-rc refuses to. Re-encoded as
UTF-8 with a BOM, which both recognise.
windows.cpp and piped_proc.cpp reached windows.h through an imported
module's global module fragment, which does not cross the boundary.
LPT.cpp and zmq_input.cpp never had it at all - the first was in an
MSBuild batch that aborted before reaching it, the second is behind
WITH_ZMQ and has not been compiled by either CI job.
The earlier sweep only looked inside #ifdef _WIN32 blocks, but these
files are gated by CMake instead, so they have no such block.
Every module unit now includes the standard headers it uses. Declarations
reaching a unit only through an imported module's global module fragment
are reachable but not visible, so ADL misses the free operators older
libstdc++ declares beside a type - reproduced on ubuntu 24.04 (libstdc++
13), where gl/vao.cpp could not compare vector iterators.
Also drops a stale editor/editorSettings.hpp from the MSVC source list,
which broke the Windows configure step, silences the deliberate
include-in-purview warning in the glm wrapper, and removes GCC support:
clang or MSVC only.
