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
