Did you see that press release about how Microsoft is taking a month off
from coding new features and dedicating everyone to fixing bugs?  I can
see an analogous headline:

"FreeBSD developers get sick of gcc's code generation, devote March to
compiler rewrite"

and in related news:

"Brett Glass finds out that FreeBSD developers are working on gcc and
suffers a nervous breakdown."
