Oh. Current Autoconf code has that. I didn't notice (but I see you
also did now):

Yuck, that's ugly. Should we have a VERSION file, changed by a commit
hook or something like that?
Hmm, distcheck is not even failing at this point:

[... happily going on ...]
If I use a subshell for redirection, the shell exits nonzero:
$ touch a && chmod -w a
$ sh -c '{ echo foo; } > a'; echo $?
sh: a: Permission denied
0
$ sh -c '( echo foo; ) > a'; echo $?
sh: a: Permission denied
1
This is bash 3.1.17(1), but also happens with 3.2.0(2); not with pdksh.
Isn't that a bash bug?
Cheers,
Ralf
