* stdio-common/Makefile (tests): Add tst-put-error.
* stdio-common/tst-put-error.c: New file. * libio/fileops.c (_IO_new_file_xsputn): If overflow fails and no more data would have to be written signal error. * libio/oldfileops.c (_IO_old_file_xsputn): Likewise. * libio/fileops.c (_IO_new_file_overflow): Use NULL not 0.
