        Bash added the "feature" to allow dropping of the leading
"0",  accepting strings: "\0nnn", "\nnn", and "\xHH".  I'm guessing that
most bash users run in a shell that has expansion turned off by default or
this would have come up before.

the xpg_echo bash option..

Lets see what this does to configure shall we.. oh, yes it fails
miserably with this bash option set.

please send this to the autoconf maintainers as well. Probably they can
add a rule detecting this kind of systems and falling back on an
alternative somewhat slower echo method..

I believe bash is broken in regards to using "any" number after
"\" as an octal value.  The shell specifications require the leading
zero for an octal constant and I don't think this problem would arise
if that was fixed.  I can forward the info to them anyway.
