I've implemented that in try_compile-targets in my clone. That topic will 
conflict with linked-usage-cleanup in the ExportImport test, so I'll wait 
until that is merged to master at least before merging to next.

I noticed that the order of paramters accepted by try_compile is not the 
same as the order passed to it by the macros. I'm not certain I got the 
parsing for it right.

Thanks,

Steve.
