While this may be true for C, I doubt it for C++. My experience (no
measurements, sorry!) with a medium-sized C++ application (~50 KLOC) is
that CPP takes a lot of time, followed by linking. The basic reason for
this is an approach to "reusability" that features a huge library
(~1Mbyte), with corresponding header files. In such a context, the
cpp:cc:as:ld ratios might look like 3:1:1:10.
