Hi Bob,

Check out http://www.apple.com/rosetta/

Rosetta translates application support on Intel-based machines so  
that Power PC apps can run on it.  There is some minimal loss of  
speed as Rosetta adds its own overhead.  You never have to install or  
configure Rosetta because it's an integral part of Mac OS X  for Intel.

If you go to Finder -> Applications, highlight an application, and  
click on cmd-i (for information), you'll be able to see whether the  
app is "Universal" (will run on either Power PC or Intel Macs) or  
"Power PC".  There's a box to check to run even a Universal app under  
Rosetta, thought I don't know why one would want to do that, except  
maybe for testing purposes.

When I got my Intel-based iMac, I copied applications and files from  
my old Power PC iMac.  In nearly 2 years with the Intel machine, I  
have never had an older application fail to run, so I'll be surprised  
if the Power PC C++ compiler does not work.

Best regards, Joe
