[Boost-build] new generator or fetaure for gui code in borland - not sure of approach to take

Hi all,
hopefully some one can point me in the right direction.

Problem:
I am trying to compile gui code using the borland compiler.  The linker requires 
access (-L definition) to the location of 1 or more .dfm file associated with 1 
or more libraries.

So for instance if I have the following Jamfiles:
----------------
guilib/Jamfile
lib GuiLib : some_form.cpp  : <link>static
     ;

----------------
main/Jamfile
exe somemain :
exe gui_test_runner : gui_test_runner ../guilib//GuiLib  : : :
     ;

GuiLib has a dependancy on a .dfm file which the exe target in main/Jamfile has 
no way of knowing about, which in turn generates a link error.

Solutions:
1. I would like to add the .dfm file to the library source list so it is picked 
up as a dependancy for the library, which could then generate a -L path for the 
link stage.
Example:
----------------
guilib/Jamfile
lib GuiLib : some_form.cpp  some_form.dfm : <link>static
     ;

2. Define a feature (similar to def-file is msvc toolset) which allows me to 
specify something in the Jamfile that can be used to generate a link line.
Example:
----------------
guilib/Jamfile
lib GuiLib : some_form.cpp  : <dfm-file>some_form.dfm <link>static
     ;

I have tried approach no 2 and had no success. approach 1 feels more right but I 
am not sure where to start.

Questions:
1. which is the best approach?
2. any examples around i can use to help me along?

any feedback appreciated
