It should be supported by all compilers.

Taxidraw is proving rather useful (thanks David), but I've spotted
something slightly odd - I'm unsure if it's the source data, or genapts,
David,
I've been playing with your logging system (/logging/log/etc. in the
property tree) and it is very slick. Good work. :-) It's very
convenient for setting up the fields you want to log and the rate and
dumping out to a file. I added an fg_command wrapper so I could set
up the fields from
