I see your point. From my point of view, it's nice to be able to
add support for something that one person needs (e.g. microsecond
timers) without requiring agreement from everyone else. And to some
extent I'm trying to avoid the inevitable "I just loaded the latest
VMMaker and now I can't compile a VM" questions. But perhaps this
causes more problems than it solves.
This thread ("Problem compiling Mac VM") seems to be a good example
of the point you are making. I wonder what John and Ian think?
