Re: atomic replacement of autom4te's output file

[Paul Eggert]

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'.
