How do add decoration to imported subroutines in Intel Compiler?

Our build machine compiles a Fortran file using the Intel compiler
v9.1.024. Doing a dumpbin on the object shows that a routine imported
from a linked-in library is specified as AYNUMI@0 and is indeed
represented as such in the lib file.
However my machine is on v9.1.037, and a dumpbin on the object created
from exactly the same ifort command line shows that object is now
looking for AYNUMI, ie. without the decoration. My link therefore
fails as the lib (created with CVF) indeed exports AYNUMI@0.
Any idea how to add the decoration that was removed presumable as a
default during the changes from 24 to 37?
