1// nx_macroprobe.nx -- does @ifdef TARGET_X86_64 resolve CONSISTENTLY across imported files?
2// nx_fcntl.nx compiled NX_SYS_FCNTL=25 (the @ifndef branch) while nx_syscalls.nx's numbers work.
3// Both use the identical @ifdef TARGET_X86_64 / @ifndef pattern. If one file takes the x86 branch
4// and another takes the riscv branch IN THE SAME BINARY, the macro is not applying uniformly.
5// expect_exit: 0 license_tier: ORIGINAL
