multiple definition of `__i686.get_pc_thunk.bx'

[Stephen Montgomery-Smith]

I am the maintainer of the port vis5d+.  I just got this email (copied 
below) saying that vis5d+ isn't building right now.

The issue seems to be that some reference to __i686.get_pc_thunk.bx is 
included twice at some point.  This variable seems to be part of an 
object file crtbeginS.o that is created by gcc or gcc45, in what seem to 
me to be very mysterious conditions.  I am rather sure that the issue 
has nothing to do with vis5d+, but rather is something to do with either 
gcc45, or libtools, neither of which I understand.

Does anyone out there have any idea of what the problem is, or how it 
can be solved?
