-systematic tests of make/make install with different --prefix configs.
-test the make install procedure starting from the tar file + svn
-test when starting from scratch or after a svn up.
-if possible tests with different compiler versions (in particular gcc4.2
 seems to be a big requirement)
-tests the results of make dist by checking if the corresponding tar (or .msi)
 files can really be used on the target platform.
-test the size of the tar files after make dist or make distsrc to make sure
 that unwanted files are not written to the tar file.
-test the make rpm or debian with validation
