+    openat2: define _GNU_SOURCE and include <fcntl.h>
+    
+    On Fedora Rawhide (glibc 2.43+), libc exposes openat2() and struct open_how,
+    so our configure script defines HAVE_OPENAT2 and the fallback definition in
+    lapi/openat2.h gets skipped. But openat20*.c never included <fcntl.h> (and
+    lacked _GNU_SOURCE), so the libc-provided prototype and struct stayed hidden,
+    so compilation failed:
+    
+      # uname -r
+      6.18.0-65.fc44.x86_64
+    
+      # rpm -qf /usr/include/fcntl.h
+      glibc-devel-2.43-1.fc44.x86_64
+    
+      # nm -D /usr/lib64/libc.so.6 | grep -w openat2
+      00000000000eb890 W openat2@@GLIBC_2.43
+    
+      # make -C testcase/kernel/syscalls/openat2
+      openat201.c:27:62: error: invalid application of ‘sizeof’ to incomplete type ‘struct open_how’
+        27 |         {&dir_fd, TEST_FILE, O_RDWR, S_IRWXU, 0, &how, sizeof(*how)},
+    
+    Define _GNU_SOURCE and include <fcntl.h> in openat2 tests to make the
+    prototype available and fix the build.
