[Boost-build] Bjam -q does not correctly detect all errors returned by tools

Hello,

I noticed a problem with executing actions where one of the commands
exits with a failure.
I'm running on Windows 2000, Boost.Build V2 (Milestone 10) from CVS,
Boost.Jam 03.1.12, and using MS VC, trying to compile an idl file. 
This is the action used:

actions compile.idl
{
    $(.IDL) <...>
    $(TOUCH_FILE) "$(<[4]:W)"  
    $(TOUCH_FILE) "$(<[5]:W)"  
}

I run bjam -q, so bjam must quit on the first error reported. When the
idl compiler returns an error, the touch commands are still executed,
and bjam thinks that the commands succeeded correctly, so it continues
building the next target. If I change the order of commands: 

actions compile.idl
{
    $(TOUCH_FILE) "$(<[4]:W)"  
    $(TOUCH_FILE) "$(<[5]:W)"  
    $(.IDL) <...>
}

then bjam -q detects correctly that the idl did not compile
successfully, so it stops.

I have no idea how this should be solved.

Best regards,

Richard Peters
