OK, build completed, no segfaults, make check gives 2 FAILs: file-io.cc and
ov-java.cc.

Do I have to add s/th to ov.java.cc tests to have them skipped by "make
check" in case of --disable-java configure option?

And do I have to put all tests for .cc files into one test block? (I put two
separate test blocks in ov-java.cc)
