Looks like gcc 4.7 will require some major code cleanup. However, today I ran across this response in a forum discussion:
Perhaps some of the 4.7 problems will be resolved by manually adding unistd.h in the preprocessor includes.

This document explains the changes in gcc 4.7:

Somebody more experienced with compilers could help by translating that information into a wiki how-to of what types of failures to expect, what types of cures will help, and when those cures need to be explicitly defined in the build process.
