--  Change references to DelftOnline and JavaLaunch in all Makefile.am files
    from absolute path on devux32 to path to third_party_open.

--  What to do with resolve_path in hydra.cpp?

--  Deal with version numbering.
    Generate (?) engines_gpl/flow2d3d/packages/flow2d3d/src/flow2d3d_version.f90
    Preferable convert to C and store version strings in GDP

--  Set our own signal handlers.

    DOL (and thus the JVM) is started before Hydra::Execute is called.
    Hydra::Execute does something stupid like dereference a NULL-pointer.
    The SEGV call stack had a Java handler, even though we're no "in" Java yet.
