I was imprecise: the Borland compiler requires all the Spirit include directives
to use angle brackets *and* to be relative to the Boost root directory. This
compiler has a weird include search scheme when double quotes are involved that
results in Spirit files to be taken partly from the external 1.6 location and
partly from the main Boost tree.

I have a working implementation, I'll post it tonight (GMT+1) from home, as I
cannot post attachments from Gmane's web interface. The gist of it is the
following function:
rule include-spirit ( properties * )
{
local result ;
local SPIRIT_ROOT = [ modules.peek : SPIRIT_ROOT ] ;
for tset in borland vc iw
{
if ( <toolset>$(tset) in $(properties) )
{
if ( $(SPIRIT_ROOT) )
{
result = <cxxflags>-I$(SPIRIT_ROOT) ;
}
else
{
echo *** spirit 1.6x required to build library with this compiler *** ;
result = <build>no ;
}
}
}
return $(result) ;
}

You can add <cxxflags>-I/path/to/Spirit16 to the Borland entry. I don't like
this solution because it causes Spirit 1.6 to be used for all the tests that
involve Spirit.
