Re: CVS autoconf testsuite failure on Tru64 unix

[Paul Eggert]

Nicolas, thanks for reporting that problem.

Noah, can you please take a look at Nicolas's bug report
<http://lists.gnu.org/archive/html/bug-autoconf/2004-12/msg00022.html>?
It seems related to the recent changes I installed, relating to
escaping for expanding, which you contributed in October.  In
particular, the first test failure is due to this command in
tests/testsuite:

    at_cmd_expanded="autoconf -t TRACE2:'${)===(}@'"

This shell command doesn't conform to POSIX, because the $ is not escaped.
So Tru64 is within its rights to reject it.
