HP-UX venus A.09.05 A 9000/712
gcc 3.1
>Description:
configure fails in gcc-3.1/gcc due to od -c output.

On HP-UX A09, `od -c' lists offset information in decimal by default,
but the configure script expects octal numbers.

This breaks the tests for endianness and floating point format.

I am aware that HP A09 is quite old, but I thought I report it anyway.
>How-To-Repeat:
HP-UX venus A.09.05 A 9000/712
./configure
...
Configuring gcc...
...
checking for CHAR_BIT... yes
checking byte ordering... unknown
configure: error: *** unable to determine endianness
>Fix:
Changing the arguments to od from `od -c' to `od -tc -Ao'.
I don't know whether other systems will break.
