It's also an excellent way to waste several days of one's life that you 
will never get back :-)

If it's only a few packages affected, a much better idea would be to 
grep through /var/wherever-portage-puts-it to find the CFLAGS for each 
package installed, determine the ones that are not correct, and emerge 
just those with 'emerge -n'. How to do this marvellous grepa nd emerge 
is left as an exercise for the reader, as I'm much too lazy to figure 
it out at almost midnight :-)

If it's most of the system that's affected, then yeah, emerge -e world 
is probably easier.
