We just downloaded 1.3 and tried to build it,
and it died saying it couldn't find "JDWPCommands.h".
That's apparently a generated header file, so I dug a
little and it looks to me like the GNUmakefile in

        ext/jpda/build/solaris/jdwpgen

doesn't do anything for an optimized build. Shouldn't it?
I'm wondering whether

  all: optimized $(GEN_JDWP_JAVA) $(GEN_JDWP_C)

should be

  all optimized: $(GEN_JDWP_JAVA) $(GEN_JDWP_C)
