The place I was unable to build world after the flex update was a 
poudriere jail.  I wasn't able to reproduce the problem on /usr/src.

However, if buildworld fails for you in the bootstrap stages (stage 1 or 
maybe stage 2c) with M4 errors then this should fix the problem:

(assuming /usr/src is the latest)

then retry the buildworld.
