  I can't reproduce this: after bootstrapping GCC at r.155680, I get:

$ nm -sn i686-pc-cygwin/libjava/.libs/cyggcj-11.dll |grep JCR
6c93ecd0 d ___JCR_LIST__
6c94382c d ___JCR_END__

Also, gcj-dbtool works for me:

$ PATH=./i686-pc-cygwin/libjava/.libs:$PATH  ./i686-pc-cygwin/libjava/.libs/gcj
-dbtool.exe  --help
gcj-dbtool: Manipulate gcj map database files

  Usage:
    gcj-dbtool -n file.gcjdb [size]     - Create a new gcj map database
    gcj-dbtool -a file.gcjdb file.jar file.so
            - Add the contents of file.jar to a gcj map database
    gcj-dbtool -f file.gcjdb file.jar file.so
            - Add the contents of file.jar to a gcj map database
    gcj-dbtool -t file.gcjdb            - Test a gcj map database
    gcj-dbtool -l file.gcjdb            - List a gcj map database
    gcj-dbtool [-][-0] -m dest.gcjdb [source.gcjdb]...
            - Merge gcj map databases into dest
              Replaces dest
              To add to dest, include dest in the list of sources
              If the first arg is -, read the list from stdin
              If the first arg is -0, filenames separated by nul
    gcj-dbtool -p [LIBDIR]              - Print default database name



What version of binutils are you using, and how do you configure your GCC
build?
