Windows, SDL3.2.4: SDL/SDL_stdinc.h has a problem with clang-tidy.exe

[t-mat]

Problem

In both of genuine VC++2022 and LLVM environment, clang-tidy.exe reports the following error:

external/SDL3/include/SDL3/SDL_stdinc.h:5972:10: error: 'strings.h' file not found [clang-diagnostic-error]
 5972 | #include <strings.h>
      |          ^~~~~~~~~~~

Reproduction

cmd.exe
cd /d "%PUBLIC%"
md SDL-issue-12238
cd SDL-issue-12238
curl.exe -o main.zip -Ls https://github.com/libsdl-org/SDL/archive/9b18e8438f5225b62dc631a3306d2205be247ce7.zip
tar.exe -xf main.zip
cd SDL-9b18e8438f5225b62dc631a3306d2205be247ce7
cmake -S . -B build -G "Visual Studio 17 2022" -A x64 -T ClangCL
cmake --build build -- /nologo /verbosity:minimal /maxcpucount /p:RunCodeAnalysis=true

Reproduce the issue with Visual Studio Community 2022 Preview

• Setup and build hello.c
• Navigate to (Menu Bar) > Project > Property > (Left pane) > Configuration Property > General > (Right Pane) > General Property > Platform Toolset
  • Change it to LLVM (clang-cl)
  • Press (Bottom Right) "Apply"
• Invoke (Menu Bar) > Analyze > Run Code Analysis > Run Code Analysis on [Project Name]
• C:\Program Files\Microsoft Visual Studio\2022\Preview\VC\Tools\Llvm\x64\bin\clang-tidy.exe reports the following error

    Error while processing C:\SDL3-Hello\hello.c.
    C:\SDL3-Hello\external\SDL3-3.2.4\include\SDL3/SDL_stdinc.h(5972,10): error G8FFBB946: 'strings.h' file not found [clang-diagnostic-error]
     5972 | #include <strings.h>
          |          ^~~~~~~~~~~
    Suppressed 1 warnings (1 in non-user code).
    Use -header-filter=.* to display errors from all non-system headers. Use -system-headers to display errors from system headers as well.
    Found compiler error(s).

Basic analysis

clang-cl.exe + clang-tidy.exe environment predefines the following symbols.

__clang_analyzer__  // clang-tidy.exe
__clang__           // clang-cl.exe
_MSC_VER            // clang-cl.exe

Therefore, the following #if is always true

SDL/include/SDL3/SDL_stdinc.h

Line 5945 in 725ee76

#if defined(__clang_analyzer__) && !defined(SDL_DISABLE_ANALYZE_MACROS)

But typical Windows environment doesn't have <strings.h>.

SDL/include/SDL3/SDL_stdinc.h

Line 5972 in 725ee76

#include <strings.h>
