Hi,
These days I stumbled across a portability pitfall with POSIX 'od', while
writing an autoconf macro. How about documenting it in autoconf?

about 'od'.

+ @item @command{od}
+ @c ---------------
+ @prindex @command{od}
+
+ MacOS X has an @command{od} program that shows an error message when any
+ of the standard POSIX options @code{-A}, @code{-j}, @code{-N}, or @code{-t}
+ is used. The only supported POSIX option is @code{-v}. On this platform,
+ the BSD @command{hexdump} program is available instead.

@item @command{sed}
@c ----------------
@prindex @command{sed}
