I'd lean against this patch. The standard behavior for Unix utilities <http://www.opengroup.org/onlinepubs/000095399/utilities/xcu_chap01.html#tag_01_07_01_04> is simply to open an output file for writing, and not to attempt to make the entire creation of the file atomic. I suggest that the user use 'make' to invoke 'autoconf'; 'make' should remove the output file for him automatically if it is interrupted while running 'autoconf'.
