OK I made up a a patch and attached it.

Or maybe "dummy"...


Unfortunately named constraints have to exist even if they are never used
as otherwise they generate a compile error. Given theres no point creating
a temp variable then may as well use an existing one. If it needs to be
explicitly stated then a comment can be added to point out that it is never
actually used but given that was never done previously then changing it to
pw_42 should suffice.

The vf_fspp.c issue should already be fixed but thank
> you for confirming I didn't miss anything.


Well attached is a patch to remove the multiply defined named constraints
anyway (just in case its useful).

Where you able to test ced0d6c1 / ticket #3472 with
> icc on Windows?


So far I havnt seen any problems with it with icl but ill run up some
proper tests and let you know.
