Linker errors when building ADATE with amd64

Hi

I'm currently working on porting the ADATE system to x86_64. I get
some linker errors when building that I'm having a hard time figuring
out.

The mlton output (with the compile SML output discarded):

The mlton command line I'm using is:

mlton @MLton fixed-heap 800m -- -link-opt '-mmodel=medium -fPIC
-static' -verbose 1 -codegen amd64 -const 'Exn.keepHistory true'
-runtime 'ram-slop 1.0' -default-ann 'allowFFI true' makespec.sml
./execute.c ./ampi_interface_mlton.c ./svd_lin_solve.c

I've played around with the link-opt's but haven't been able to change
the outcome.

Can someone tell me what I can do to fix this?
