The contents of TEST_SYSCALL_NAME and STRUCT_STAT macros was subject to macro expansion when used in definitions of TEST_SYSCALL_NR, TEST_SYSCALL_STR, and STRUCT_STAT_STR macros. As some libcs, e.g. musl libc, define lfs64 names as macros (stat64 as stat, lstat64 as lstat, etc.), this might result to incorrect expansion of TEST_SYSCALL_NR, TEST_SYSCALL_STR, and STRUCT_STAT_STR macros. To avoid this problem, define these macros directly and remove TEST_SYSCALL_NAME macro. * tests/_newselect.c (TEST_SYSCALL_NAME): Remove. (TEST_SYSCALL_NR, TEST_SYSCALL_STR): New macros. * tests/fcntl.c: Likewise. * tests/fcntl64.c: Likewise. * tests/fstat.c: Likewise. * tests/fstatat64.c: Likewise. * tests/lstat.c: Likewise. * tests/newfstatat.c: Likewise. * tests/select.c: Likewise. * tests/stat.c: Likewise. * tests/fstat64.c (TEST_SYSCALL_NAME): Remove. (TEST_SYSCALL_NR, TEST_SYSCALL_STR, STRUCT_STAT_STR): New macros. * tests/lstat64.c: Likewise. * tests/stat64.c: Likewise. * tests/fstatx.c (TEST_SYSCALL_NR, nrify, nrify_): Remove. * tests/lstatx.c: Likewise. * tests/struct_flock.c (TEST_SYSCALL_NR, TEST_SYSCALL_STR, nrify, nrify_, stringify, stringify_): Remove. * tests/xselect.c: Likewise. * tests/xstatx.c: Check TEST_SYSCALL_STR instead of TEST_SYSCALL_NAME. (STRUCT_STAT_STR, TEST_SYSCALL_STR, stringify, stringify_): Remove. [!STRUCT_STAT] (STRUCT_STAT_STR): New macro.
