MSVC tool cpp source RSP combination problem

Hi there,

In msvc.jam, there is three lines of comment saying:

# is it possible to combine these?
# make the generators non-composing, so that they don't convert each 
source
# into separate rsp file.

I wonder if someone can solve this issue? Combining all cpp sources 
into one RSP file greatly *improves* compilation performance. In 
contrast, current implementation is *MUCH* slower then using DEVENV 
VC project file because VC DEVENV puts app cpp files into a single 
RSP file.

Bjam is a good tool in every aspect. It just happen that I have adopt 
it into several mission-critical projects. And build-time of Bjam in 
VC project is significant slower than using DEVENV. It's really 
discouraging. So any helps are greatly appreciated.
