>Description:
 * If libgcj.a is built with optimization, gij and jv-convert won't link:
   Affected files:
    java/lang/Class.java
     -> if -O3 or higher is used, hackTrampoline and checkMemberAccess are no
        longer present in the object file.
     Probable cause: -O3 turns on -finline-functions, and the Java compiler
      treats incorrectly inlines them.
    java/util/GregorianCalendar.java
    java/util/TimeZone.java
    java/util/zip/ZipEntry.java
     -> These miss LJv0, LJv1, ... entries if optimizing; -O0 is required.
   <This bug has also been submitted to the gcc-bugs list>
>How-To-Repeat:
Try to build the affected files with optimization.
