[Boost-build] Jamfile help request

so please specify exactly what you do, what you get, what
> you expect,  and why.

I want to run build the library for borland.  However, the
borland compilers don't  work with later versions of spirit.
The do work with spirit 1.6x.  So, If one has a copy
of spirit1.6x in some directory, and that directory is
placed in the list of include directories, the serialization
will build and most of the tests should pass.  So I want
builds using the borland compiler to add the directory
name contained in $(SPIRIT_ROOT) in the list of
include directories.  If $SPIRIT_ROOT) isn't specified
I want to emit an error message.

When I currently do this now, I do have SPIRIT_ROOT
defined, but the build doesn't seem to add the contents
of this variable  to the list on include files.  In fact, puting
an "echo" statement into rule include-spirit emits nothing
which suggests this rule isn't called at all.

The reason that I want to do this is so the the library
for borland can built and the tests run.

Thanks for your help.
