Targets, the target's C compiler (FINCH_CC) for linking, C import for the target (--target to libclang, its headers), the AAPCS64 and Microsoft x64 ways of passing structs by value (and the System V one), dllexport for libraries on Windows, .exe names, and running the program through wine or qemu-aarch64. std/ gets time_windows.fch and proc_windows.fch: a module has a version per system (name_windows.fch, name_macos.fch, name_linux.fch) that wins over name.fch. stdin, stdout and stderr work where C makes them macros. Run for real: all 27 programs under tests/run and tests/new pass on ARM64 Linux under qemu and on Windows under Wine (MinGW), structs by value and callbacks included. macOS is only checked as far as clang accepts the IR; there is no emulator for it here.
