Problem with building L4Linux

[Nuno Santos]

Hi Adam

Thank you very much for your help. It's indeed a problem with  
compiling ocaml. As you suggested, tagging it as 'broken' let's  
compile go through.

I traced the command that leads to this error (from directory /local/ 
l4re-snap/l4re-snapshot-2010111519/obj/l4/x86/pkg/ocaml/build/stdlib/ 
OBJ-x86_586-l4f):

$ ocamlopt -g -warn-error A -nostdlib -c -o stream.cmx /local/l4re- 
snap/l4re-snapshot-2010111519/src/l4/pkg/ocaml/contrib/stdlib/stream.ml
/tmp/camlasm25fea1.s: Assembler messages:
/tmp/camlasm25fea1.s:580: Error: junk `lazy_force(%rip)' after  
expression
/tmp/camlasm25fea1.s:580: Error: suffix or operands invalid for `lea'
/tmp/camlasm25fea1.s:785: Error: junk `lazy_force(%rip)' after  
expression
/tmp/camlasm25fea1.s:785: Error: suffix or operands invalid for `lea'
Assembler error, input left in file /tmp/camlasm25fea1.s

My version of ocamlopt is 3.10.2, and the distribution is Debian 5.0.6.

Thanks again,
--Nuno
