Yeah, the linkage between java.util.Date and gnu.java.locale.Calendar
is weak -- Date only references Calendar via reflection. GNU ld
doesn't understand this sort of linkage, so it doesn't include
gnu.java.locale.Calendar when creating a static binary.

Here's the standard prelude I throw into all my gcj programs to force
the linker to include all the required classes:

    // static references to these classes ensure that the linker will include them
    private static Class c1 = gnu.java.locale.Calendar.class;
    private static Class c2 = java.util.GregorianCalendar.class;
    private static Class c3 = gnu.gcj.convert.Input_ASCII.class;
    private static Class c4 = gnu.gcj.convert.Input_UTF8.class;
    private static Class c5 = gnu.gcj.convert.Input_8859_1.class;
    private static Class c6 = gnu.java.locale.LocaleInformation.class;
    private static Class c7 = gnu.gcj.convert.Output_ASCII.class;

To the other GCJ people: are there any disadvantages to putting
private static foo.class references in the java.* classes so that
static links work properly without this hack?

Probably because you're dynamically linking against libgcj.so, which
includes the whole Java library. If you compile with --static you
should see the same problem on Linux.
