I've a design issue: suppose we've link-incompatible property, for example
<rtti>, and the following project:
exe a : a.cpp l ;
lib l : l.cpp ;
Then both targets will be build with default value -- <rttin>on. No problem.
Another example:
exe a : a.cpp l : <rtti>on ;
lib l : l.cpp : <rtti>off ;
Here, first targets *explicitly* asks for <rtti>on and uses another one, which
explicitly requires something else. Since <rtti> is not link-compatible, this
is an error. Now the question:
exe a : a.cpp l ;
lib l : l.cpp : <rtti>off ;
The first target will be build with default value <rtti>on. What about the
second:
1. Should we request it with <rtti>on and get an error, or
2. Should we request if without any <rtti> setting and allow it to be
built with <rtti>off
I think (1) is way safer. But interested in other opinions.
