I am a bit confused by this reply.

The library itself, or its source files, do not need any defines. What I 
need is the library's usage requirements to cause a <define> to appear in 
all client targets, such that each cpp file in a client target gets a 
"-D__BASE_FILE__=<n>" passed to the compiler, where <n> is the (complete) 
name of the cpp file (from the client target, not the library) being 
compiled.

Clearly, boost-build has the cpp file when it launches the compiler, so it 
seems to me that at least there should be a way to modify the msvc support 
in boost-build to always pass a -D on the command line to specify the cpp 
file being compiled. Even if the solution is hard-coded in the msvc support, 
it would be of great help to me.

Thanks a lot for your time,
Emil
