'od' portability problem

[Bruno Haible]

Hi,

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

        * doc/autoconf.texi (Limitations of Usual Tools): Add a paragraph
        about '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.
