Hi Quentin,

> target=i486-linuxaout.

The problem here is that the aout file format does not specify the 
address size of the objects it contains, so the BFD library does not 
know whether the objects are 32-bit or 64-bit.  Instead nm defaults to 
using the bitsize of the host.

I have uploaded a patch which improves nm's heuristic.  Now if the BFD 
library cannot tell it the bitsize of the target it will look at the 
target format's name.  If the string "64" occurs anywhere in the name 
then it will assume a 64-bit bitsize, otherwise it will assume a 32-bit 
bitsize.  Not perfect but I think that it should work most of the time.

Please try out the patch and let me know what you think.

Cheers
   Nick
