Przemyslaw Czerpak bf68197ca0 2008-04-09 20:42 UTC+0200 Przemyslaw Czerpak (druzus/at/priv.onet.pl) 
* harbour/ChangeLog
  * harbour/harbour.spec
    * reverted translation to UTF8 - Tomaz please check your editor
      settings and disable automatic translation to UTF8. It's not
      the first as such situation happens.

  * harbour/include/hbclass.ch
    + added two missing PP directives
    ! protected against some repeated external definitions

  * harbour/source/pp/Makefile
  * harbour/source/pp/hbppgen.c
  * harbour/source/pp/ppcore.c
  * harbour/source/common/hbver.c
  * harbour/source/common/hbverdsp.c
  * harbour/source/main/harbour.c
  * harbour/source/vm/cmdarg.c
  * harbour/utils/hbpp/hbpp.c
  * harbour/include/hbpp.h
  * harbour/include/hbcomp.h
  * harbour/include/hbver.h
  * harbour/include/hbapi.h
  * harbour/make_vcce.mak
  * harbour/make_b32.mak
  * harbour/make_vc.mak
  * harbour/make_gcc.mak
    + added support for dynamically set during compilation ChangeLog entry
      ChangeLog ID and SVN revision and compilation flags
      Now hbppgen creates in include directory hbverbld.h file with
      information extracted from ChangeLog. New hbppgen parameters:
         Syntax:  ./hbppgen <file>[.prg] [options]
         Options: -i<path>       add #include file search path
                  -c[<file>]     look for ChangeLog file
                  -o<file>       creates .c file with PP rules
                  -v<file>       creates .h file with version information
                  -w             write preprocessed (.ppo) input file
                  -q             disable information messages
    + added new C functions:
         int hb_verSvnID( void )
            - retrieves ChangeLog SVN revision number
         const char * hb_verSvnChangeLogID( void )
            - retrieves a static buffer containing ChangeLog ID string
         const char * hb_verSvnLastEntry( void )
            - retrieves a static buffer containing ChangeLog last entry string
         const char * hb_verFlagsC( void )
            - retrieves a static buffer containing build time C compiler
              flags in C_USR envvar
         const char * hb_verFlagsL( void )
            - retrieves a static buffer containing build time linker
              flags in L_USR envvar
         const char * hb_verFlagsPRG( void )
            - retrieves a static buffer containing build time Harbour compiler
              flags in PRG_USR envvar
    + added new default PP defines which can be used in .prg code compiled
      by Harbour compiler: HB_VER_LENTRY, HB_VER_CHLID, HB_VER_SVNID

  * harbour/source/rtl/gtxwc/gtxwc.c
    * formatting

  * harbour/source/rtl/gttrm/gttrm.c
    ! fixed redrawing GPM mouse pointer after screen updating

  * harbour/source/rtl/gtstd/gtstd.c
  * harbour/source/rtl/gtpca/gtpca.c
    * updated for compilation even if some POSIX macros are not supported
      f.e. problems with some DJGPP versions reported recently

  * harbour/source/debug/dbgentry.c
  * harbour/source/debug/dbgtobj.prg
  * harbour/source/debug/dbgbrwsr.prg
  * harbour/source/debug/dbgthsh.prg
  * harbour/source/debug/tbrwtext.prg
  * harbour/source/debug/dbgwa.prg
  * harbour/source/debug/debugger.prg
  * harbour/source/debug/dbghelp.prg
  * harbour/source/debug/dbgtarr.prg
    ! Fixed object inspector in the debugger.
    ! Added HbDbBrowser:invalidate() message. Fixes work area browsing in debugger.
    ! Added an minimalistic TBrowse implementation that is just enough
      for internal use by the debugger. Fixes miscellaneous problems e.g.
      when debugging a piece of code with RELATIONs turned on.
    Fixes by Phil Krylov borrowed from xHarbour.
