Release 3.1.1 (Public Release - 1996.09.27)

- Added preliminary support for the Win32 environment (WINSOCK library).
  Replaced the mscw31.h config include with cfwin32.h.  The dcmnet library
  now uses appropriate WINSOCK socket calls (send instead of write, recv
  instead of read, closesocket instead of close).
  Added:   config/include/cfwin32.h
  Removed: config/include/mscw31.h
  Affects: config/include/osconfig.h
           dcmnet/libsrc/dul.cc
           dcmnet/libsrc/dulfsm.cc
           dcmnet/include/dcompat.h
           dcmnet/apps/*.cc

- Preliminary support for IBM AIX systems using the IBM C Set++ compiler.
  It is necessary to indicate that some system include files
  have C linkage.  Moved the BEGIN_EXTERN_C and END_EXTERN_C defines
  from dcmnet/include/dcmnet.h to config/include/osconfig.h so that they
  are always available.  Some of the most affected files have been modified
  to use BEGIN_EXTERN_C/END_EXTERN_C but many more need changing.
  Affects: config/configure.in
           config/include/osconfig.h
           dcmnet/include/dcompat.h
           imagectn/libsrc/dbindex.cc
           imagectn/libsrc/dbstore.cc
           imagectn/libsrc/dbutils.cc
           imagectn/apps/imagectn.cc
           imagectn/apps/scemove.cc
           imagectn/apps/scestore.cc
           imagectn/apps/ti.cc
           imagectn/apps/tinet.cc
           imagectn/apps/tiui.cc
           dcmnet/apps/findscu.cc
           dcmnet/apps/storescu.cc

- Preliminary support for IBM AIX systems using the IBM C Set++ compiler.
  Corrected various small syntax errors and warnings not noticed by other
  compilers (e.g. mismatch between method definition in .h and .cc files,
  used before set warnings, const to non-const assignment).  Changed flock_t
  to struct flock.  Renamed the support program wlistctn/wwwapps/preplock.c
  to preplock.cc to
  avoid a compiler crash.
  Affects: dcmdata/libsrc/dcdicdir.cc
           dcmdata/libsrc/dcdirrec.cc
           dcmnet/libsrc/assoc.cc
           dcmnet/libsrc/dcompat.cc
           wlistctn/libsrc/wrklstdb.cc
  Removed: wlistctn/wwwapps/preplock.c
  Added:   wlistctn/wwwapps/preplock.cc

- Added a pre-generated version of a builtin data dictionary.  This file
  can be included in a library instead of dcdictbi.cc and was generated
  via the mkdictbi program (in dcmdata/libsrc).  Currently a builtin
  data dictionary is not used per default.  It has been found useful
  for systems which do not support environment variables making it
  more difficult to find a data dictionary to load (e.g. Macintosh).
  Added:   dcmdata/libsrc/dcdictzz.cc

- Removed the versions of cmdlnarg.cc and cmdlnarg.h found in dcmdata/apps
  and dcmnet/apps and added one single version to dcmdata/include and
  dcmdata/libsrc (now part of the dcmdata library).
  Removed: dcmdata/apps/cmdlnarg.h
           dcmdata/apps/cmdlnarg.cc
           dcmnet/apps/cmdlnarg.h
           dcmnet/apps/cmdlnarg.cc
  Added:   dcmdata/include/cmdlnarg.h
           dcmdata/libsrc/cmdlnarg.cc
  Affects: dcmdata/apps/Makefile.in
           dcmnet/apps/Makefile.in
           dcmdata/libsrc/Makefile.in

- Added preliminary support for the Macintosh environment (GUSI library).
  Affects: dcmdata/libsrc/mkdeftag.cc
           dcmdata/libsrc/mkdictbi.cc
           dcmdata/apps/*.cc
           dcmnet/include/dcompat.h
           dcmnet/libsrc/dul.cc
           dcmnet/libsrc/dulfsm.cc
           dcmnet/apps/*.cc
           config/include/cfmwerks.h
           config/configure.in

- Added a separate table of Storage SOP Class UIDs (useful during
  association negotiation).
  Affects: dcmdata/libsrc/dcuid.cc
           dcmdata/include/dcuid.h
           dcmnet/apps/storescu.cc
           dcmnet/apps/storescp.cc
           imagectn/apps/imagectn.cc
           imagectn/apps/imagectn.h
           imagectn/apps/scemove.cc

- Added SOP Class UIDs for Radiotherapy Objects.
  Affects: dcmdata/libsrc/dcuid.cc
           dcmdata/include/dcuid.h
           dcmnet/libsrc/diutil.cc

- Added data dictionary tags for Radiotherapy Objects.
  Affects: dcmdata/libsrc/dicom.dic
           dcmdata/include/dcdeftag.h

- Corrected erroneous setting of an error flag when inserting an
  attribute into an Item (via Item::insert(...)) and the attribute
  was already present.  Now the error flag is only set if replaceOld
  is FALSE and an attribute already exists.
  Affects: dcmdata/libsrc/dcitem.cc

- Eliminated lingering reference to a G++ lib_error_handler.  The dcmdata
  library should now be independent of libg++.
  Affects: dcmdata/libsrc/dcentset.cc

- Added optional code to the dcmdump program to restrict its
  output to specified named tags.  Based on a suggestion from
  Larry V. Streepy, Jr.  (mailto:streepy@healthcare.com).
  Affects: dcmdata/apps/dcmdump.cc
           dcmdata/docs/dcmdump.txt

- Added capability to search data dictionary by tag name.  The
  source code for these changes was contributed by Larry V. Streepy,
  Jr., Chief Technical Officer,  Healthcare Communications, Inc.,
  (mailto:streepy@healthcare.com).
  Affects: dcmdata/include/dcdicent.h
           dcmdata/include/dcdict.h
           dcmdata/include/dcentbst.h
           dcmdata/include/dcentdef.h
           dcmdata/libsrc/dcdict.cc
           dcmdata/libsrc/dcentbst.cc

- Removed code which generated an error if DcmFileStream::Tell(void)
  was called when the stream was in write mode.  This behaviour was
  causing DcmDicomDir::write(...) to always fail.  In particular, this
  error was causing the program mknldir to write a DICOMDIR file
  containing only a meta-header.
  Affects: dcmdata/libsrc/dcstream.cc

- Corrected missing () when calling function stack.card() used
  in nextObject(...).  GNU C++ did not detect this error, it was
  discovered when compiling under MetroWerks C++ on a Power Mac.
  Affects: dcmdata/libsrc/dcitem.cc
           dcmdata/libsrc/dcsequen.cc
