dbx: Using "/net/malloc.sfbay/export/VMs/latest-JDK/solaris-sparc/bin/java"
changes (topic)
The major new features of this release relative to 6.0 are:

o The dbx environment variable "cfront_demangling" has been removed.
  The "-F" option to dbx (allow cfront-demangling) has also been removed.
  Use an earlier version of dbx to get cfront support.
o This release continues to support Fortran intrinsics on Intel, even
  though the Intel Fortran compiler was not shipped with WorkShop 6.
  The next dbx release will not support Fortran intrinsics on Intel.
