Our project (Shotwell) does not use autotools, but it has a hand-crafted 
Makefile that achieves exactly what you described: if a .vala files does 
not change then a .c file is not regenerated, and we can use make -j to 
build all the .c files in parallel.  In my earlier message I wasn't 
talking about the speed of compiling the .c files (which is 
satisfactory), but rather the speed of the 'valac --ccode' step which 
converts the Vala files to C.
