For short-lived applications where time is of the essence or where
they are used frequently, start-up time becomes important.  I believe
that grep may very well fall into this category.

On the system I'm using, compiling a trivial program as C++ rather
than C produces a binary that has 3 extra dynamic load-time
dependencies.  I just performed some timings and they do indeed show a
significant hit to start-up-and-exit just from switching from C to

(Of course, prelinking can help to some extent.)
