Re: [Boost-build] Project requirements acting weird

The problem with user-config or site-config is that the <cflags> I need 
propagated are warnings, and that they differe for release and debug.

Besides, I think you're incorrect when you say that <cflags> are not 
propagated, because like I said in my original post, with my setup they are 
propagated sometimes. Here is my setup:

Jamroot
    |
    +--- Jamfile 1
            |
            +--- Jamfile 2
                       |
                       + Jamfile 3

If I put the <cflags> that disable warnings in the project defined in 
Jamroot, or in Jamfile2, or in Jamfile3, it all works fine, and I can see
the flags on the command line when compiling Jamfile3 .cpp files.

But if I put them in Jamfile1, then they don't get propagated. Am I 
experiencing a bug? What's the correct behavior here, are you sure that the 
intention was not to propagate <cflags>?
