Yeah, I was puzzled by that too, but the OP has since confirmed that his 
problem was, in fact...

Actually, that alone should have been sufficient to upgrade *both* G++ 
*and* GCC, (because G++ requires GCC, but not vice-versa, and mingw-get 
"knows" this).  Ultimately, it should also be able to deduce that, when 
G++, (or any of the other language components which also requires GCC), 
is installed, then GCC alone cannot be upgraded without also upgrading 
the dependent language package(s).  However, the code for performing 
such reverse dependency look-ups isn't ready for deployment yet -- I am 
working on it at present -- so in the meantime, you need to specify all 
of the languages you have installed, to mingw-get individually, (as a 
space separated list in a single command if you prefer), if you want 
them to continue to work after a GCC upgrade.
