Re: [Bug ld/1150] undefined reference to `_mpi_sgi_init'

Hi Michael,

Great - I will check that patch in then as a first step in resolving 
this PR.

Ho Hum.

Yes - they can be handled differently, and presumably they are being 
treated differently in this case.

Can you investigate this part of the problem ?  Basically you need to 
find where this undefined symbol is being detected.  It will almost 
certainly be just before some code that calls:

  link_info->callbacks->undefined_symbol

somewhere in the BFD library code.  Alternatively if you make those Irix 
system files available to me, I can have a go - BUT ... I am about to go 
off and work at a client site for a month or so, so I will not be able 
to put as much time into binutils work.

Cheers
