One of our developers has discovered the reason why a bad property is not correctly reported by boost-build:

I think the $(e) should be $(property) share/boost-build/src/build/property.jam line 576:

--- a/share/boost-build/src/build/property.jam
+++ b/share/boost-build/src/build/property.jam

             else
             {
                 import errors ;
-                errors.error "'$(e)' is not a valid property specification" ;
+                errors.error "'$(property)' is not a valid property specification" ;
             }
         } else {
             local attributes = [ feature.attributes $(feature) ] ;

to test I've got this target with a bad property:

alias CPU_H2I : : : : blah ;

with $(e) you get no error message:

fixed with the $(property) I get the error message:

The change was introduced in 4fecb208800cd6dd3485a36461ab6e5649b4475d.  Can this be fixed? A patch is attached.

Thanks,

Chris
