I am not that good with CVS, are there any changes since last night and 
today? I did this about 30 minutes ago and it builds correctly.
However the problem is not solved, yet. Once I change configure.in to 
remove the i2c detection. (I modified this file a couple of weeks ago 
without any problems) And then do make.
I still get the same error as above. So for some reason regenerating 
files like configure (from configure.in) and probably Makefile (from 
Makefile.am) produces incorrect results.

Sorry, you are richt. it is not really cached in this file.but there is 
in a situation a autom4te.cache directory created that, possibly cashes 
stuff.

I did this and that is how I found out that there is some sort of 
caching somewhere. There are files used when processing configure.in, 
that are recreated by that same process. There is some sort of circular 
dependency in there.

All this is probably related to an incorrectly recreated Makefile om my 
system.

All this is really strange.

When I take out the AC_PYTHON_DEVEL line in configure.in followed by 
make, then everything goes well. Inserting AC_PYTHON_DEVEL again, breaks 
it again.
