rtems6's rename() implementation errors with EEXIST when the rename-to filename exists, even when renaming a file to itself or when renaming a nonexisting file. Adjust expectations.
Regstrapped on x86_64-linux-gnu, also tested with a cross to aarch64-rtems6. Ok to install? PS: https://devel.rtems.org/ticket/2169 doesn't seem to suggest plans to change behavior so as to comply with POSIX. for libstdc++-v3/ChangeLog * testsuite/27_io/filesystem/operations/rename.cc (test01): Accept EEXIST fail on self-rename, on rename of a nonexisting file, and on rename to existing file. Clean up p1 in case it remains. * testsuite/experimental/filesystem/operations/rename.cc (test01): Accept EEXIST fail on self-rename, and on rename to existing file.
