To be pedantic: grepping for 'VEC (' in gcc/ gives ~1750 hits.  But a
number of those are the X*VEC allocation functions and things like
CLASSTYPE_METHOD_VEC; cutting those out ("fgrep 'VEC (' | egrep -v
'[A-Z][A-Z_]+VEC ('") or similar gives a bit over 800 VEC instances that
use spaces.

grepping for 'VEC(' gives 1300+ hits.  That's a lot of creeping laxity. :)
