Yes. OTOH the compile time and memory use for the v2 patchkit itself look
reasonable.

He gave the absolute numbers, so you can calculate this yourself :)
empty.c 3KB, big-code.c 6MB, influence.i 400KB, kdecore.cc 4MB and 8MB (v2
patchkit).

This strangely is not the case for influence.i and kdecore.cc.
Ciao,
Michael.
