Ability to add compiler flags

Okay, thanks for the responses, all. However, I've tried setting the definition up to initialize the variables, and it makes no difference. I was guessing that that had something to do with when the class variables were actually instantiated, but didn't know for sure.

Follow-up: after a number of changes elsewhere in the code, for some reason, setting variable values at the point of definition started working, and the error went away. I'm not sure why minor changes elsewhere in the code caused that to work; it should work, but wasn't when I first tried it. Most of the changes were inserting debugging statements. Go figure. One possibility: I was having trouble getting VMD to retain and obey preference settings. That one, too, sorted itself out after some fiddling.
