renameat() does not fail with EBADF when it should

[bhaible]

POSIX ​https://pubs.opengroup.org/onlinepubs/9799919799/functions/rename.html specifies that the renameat() function "shall fail" with error code EBADF if "The old argument does not specify an absolute path and the oldfd argument is neither AT_FDCWD nor a valid file descriptor open for reading or searching, or the new argument does not specify an absolute path and the newfd argument is neither AT_FDCWD nor a valid file descriptor open for reading or searching."

This does not work in Haiku hrev57823 (from 2024-07-15): it fails with error code ENOENT instead.

How to reproduce: Compile and run the attached test program.

gcc -Wall foo.c
./a.out

Expected output:

ret = -1, errno == EBADF
ret = -1, errno == EBADF
OK

Actual output:

ret = -1, errno == No such file or directory
ret = -1, errno == No such file or directory
a.out: foo.c:41:main: !fail
