I think that change was proposed by Kevin Ryde in June <http://mail.gnu.org/archive/html/autoconf-patches/2003-06/msg00009.html> and was later installed into Autoconf.

Besides \x, <http://groups.google.com/groups?selm=9ro8ef%2427l6%241%40FreeBSD.csie.NCTU.edu.tw> says that Tru64 "cc -std" defines __STDC__ to be 0. It's clearly more conservative to use -std1, but perhaps if -std1 disables some useful extensions then we should revisit this issue.
