Hello, I just ran into a small issue checking out on Linux (Ubuntu 14.04)
to an exFAT drive.
The specific error I received was:
svn: E38: Can't set permissions on
'/media/exFAT_drive/myrepo/.svn/tmp/svn-5fj4RP': Function not implemented
I believe this issue stems from an incorrect check for why the permissions
change failed. In subversion/libsvn_subr/io.c on line 895 this error is
first detected from apr_file_perms_set(fname_apr, perms); And on line 955
there is a check for APR_STATUS_IS_ENOTIMPL which unsets the error when it
stems from APR platform issues.
But I think in this case, its the actual filesystem, not APR, which doesn't
support permissions changes, but svn dies out rather than ignoring the
error.

Looks like I introduced this problem while improving tempfile handling
some years ago.
Can you try this patch, please?
