yes, in the build process auto.inc is only depending on auto.c but in
the real world this is not true. To fix this we would probably need to 
create dependencies with gcc -MM (can we use gcc, or would romcc have to
do this? Eric?) I did this dynamically for the flashrom utility a while
ago, but for all of LinuxBIOS this would be a major task.

One thing that desperately needs to happen is to pack all the
preprocessor macros into a .h file and include it, be it by replacing
all of them with a single --include preproc.h.

This has been wasting many hours of my time when the config mechanism
decided to calculate some negative offsets that would end up with a
compiler line including -DFOO=0x-fff3 leading to really crappy error

The way it is now its a complete waste of time to even look at the
compiler warnings. Which has by accident annoyed other people on this
