I ran a quick test with ccache and ./configure. Using bogofilter's
configure script (because it was available):

before installing ccache:

3 runs of ./configure averaged 6.07s

... installed ccache ...

next run took 6.5 sec (slower than before)
next 3 runs averaged 4.96s (18.4% better than before)

conclusion: ccache _does_ help ./configure

David
