Hi Larry, 

Thanks

I installed only the gcc4 compilers (all of them, v4.5.3), but I didn't even 
look for cross compilers.

What is the name of the cross compilers (would they be those that 
include 'mingw' in the name?  Not having installed, them, perhaps this is a 
naive question, but will they live alongside the gcc4 compilers without the 
names of the compilers clashing?  I recalled something about mingw, but 
thought that was a completely different approach to having gcc on Windows, and 
in the versions included with RTools, the names of the programs there would 
definitely collide with those for gcc4

Thanks again

Ted
