I would prefer the normal version statement to work like that directly
though.
This still doesn't solve my problem though, all it does is remove the
usage of the version statement, which seems... pointless :S
From what can I see you have a few different posssible versions but when
no version is defined you can select a default version based on other
stuff like windows operating system. Rather than modify the versions or
add aditional to match the system you can create complex 'static if'
statements which also are a compile time feature but can have other static
ifs and logical comparisons like '&&' and '||'. When you have put the
right checks in you can match your select target systems all within a
single static if.
