A little hacking later, I see that the search path for cl.exe does not 
include the changes to the %PATH% environment variable made in the batch 
file evc8.bat, called by <setup> parameter in user-config.jam. I'm sure 
bjam is at least somewhat aware of that batch file because it says:

notice: [msvc-cfg] condition: 
'<toolset>msvc-8.0~stlport5.2/<architecture>/<address-model>', setup: 
'call "C:/nan/stl/STLport-5.2.1/evc8.bat" x86 >nul

(##Hack details

I found place to hack by looking in output resulting from 
--debug-configuration, which was very useful. Hack was to add this function:

rule xxPrint ( varname : varval * : vartag )
{
   if $(varval)
   {
     ECHO "xxPrint var ($(varname)) val ($(varval)) tag ($(vartag))" ;	
   }
   else
   {
     ECHO "xxPrint var ($(varname)) val (-EMPTY-) tag ($(vartag))" ;	
   }
}

and then call it in find-tool like this:
     local none = [ xxPrint "path" : $(path) : "find-tool" ] ;

result clearly showed that path was just my default %PATH% environment 
variable, not including any modifications.

end hack details##)

Any ideas?
