Current

At the moment conditioning is done like that 

<if platform="windows" build="workbench"/>

Which means enabled for 

windows and workbench

<ifnot platform="windows" build="workbench"/>

Which means enabled for 

everything but (windows and workbench)

<if platform="windows"/>
<if platform="unix"/>

Which means enabled for 

windows or unix

Something a bit more complicated like enabled for workbench on everything but windows is not possible and would have to be expressed as 

<if platform="unix" build="workbench"/>
<if platform="macintosh" build="workbench"/>
<if platform="vxworks" build="workbench"/>

Proposal

If the conditioning would be done like this 

<condition>
    <platform isnot="windows"/>
    <build is="workbench"/>
</condition>

Which would mean 

every platform but windows and workbench

Or a more complex example 

<condition>
    <platform is="windows"/>
    <build is="workbench"/>
    <multithreaded is="true"/>
</condition>
<condition>
    <platform isnot="windows"/>
    <platform isnot="macintosh"/>
    <multithreaded is="true"/>
    <custom name="somevar" is="true">
</condition>

Which would mean 

(windows and workbench and multithreaded) or (not windows and not macintosh and multithreaded and somevar=true)

We should have enough flexibility to allow complicated cases as well.
