SDL_ELF_NOTE_DLOPEN of SDL_dlopennote.h is currently designed to be used unconditionally.

SDL/include/SDL3/SDL_dlopennote.h

Lines 102 to 109 in 45d65f6

#if !defined(SDL_PLATFORM_UNIX) || defined(SDL_PLATFORM_ANDROID)
/* The dlopen note functionality isn't used on this platform */
#ifndef SDL_DISABLE_DLOPEN_NOTES
#define SDL_DISABLE_DLOPEN_NOTES
#endif
#endif /* SDL_PLATFORM_UNIX || SDL_PLATFORM_ANDROID */
#if defined(__ELF__) && !defined(SDL_DISABLE_DLOPEN_NOTES)

However, it cannot be used with an (older) toolchain not supporting variadic macros.

Compiling testdlopennote.c of this PR fails with the error below (when using MSVC 6):

testdlopennote.c(13) : error C2059: syntax error : 'string'

Defining SDL_DISABLE_DLOPEN_NOTES does not help since it is already defined (Windows is not a unix platform).
