Done.  :)  Odd that they'd go to all this effort to support so many compilers 
and then tell you to switch compilers...

Just out of curiosity, Matt, what distribution are you using?  I noticed 
sometime ago that I wasn't the only Mandrake drone around here, and 
previously I had attributed this bug in Audacity to be more or less caused by 
something Mandrake did, and figured it would go away if I ignored it.  (And 
since it didn't result in the loss of any data, it was only a minor 
inconvenience)

The Czechs announced after Sputnik that they, too, would launch a satellite.
Of course, it would orbit Sputnik, not Earth!
