I've no experience with this myself but if I remember some other people's
similar pursuits from the past correctly, differences where mostly of the 
type that could be shifted one way or the other by setting a few more flags 
or altering values of existing flags.  I came away with the impression that 
gcc/g++ was competitive with VC++, each with slight advantages in different
areas.  Someone else may have specifics that prove this not to be the case
though....
