I had the same problem and did an "emerge -v lib-compat gcc" and it worked. Hope it helps.
could you post your config.log file ?
I get the same error, so I will. It's too big to let me post here though, so it's available at: http://yallara.cs.rmit.edu.au/~abolte/config.log

I used "emerge -v lib-compat gcc" here in my box and it worked fine.
