Hi,

this is probably by design, but when using e.g. bjam -d+2 I don't get the 
contents of the response files output to screen. IIRC the -d+2 option means 
dumping the commandline, so I guess it really makes sense.

However, it makes it hard to find out the exact options passed to the 
compiler. I was trying to use the "using <toolset>" statement to add some 
default parameters to a specific toolset, and couldn't make it work. 
Eventuall I fixed it by adding them as requirements to the default project 
in the Jamfile. But even then I wondered for a long time why _that_ did work 
when I couldn't see the options being added when using "bjam -d+2".

Would it be possible to add the response file contents to the output of 
the -d+2 option (or add another option)? Good idea / bad idea?

I'm using bbv2 from CVS together with VC 8.0.
