I assume this upgrade offer is coming from the Mac App Store. I'm not sure why it would offer you a version of Xcode that's not compatible with your OS. It's supposed to know when something requires a newer OS, and only display it as an "incompatible update" which cannot be installed. That's what happens for me on Sierra.

I can't really diagnose the problem based on that description. Upgrading to High Sierra will not fix the gcc49 build failure, but if you'd like to upgrade to High Sierra anyway and are having trouble, please let us know your exact computer model, and the specific error messages you're encountering.
