harbour-core/harbour/source/compiler/hbstripl.c
Przemyslaw Czerpak fbd8b70d4b 2006-03-28 13:00 UTC+0200 Przemyslaw Czerpak (druzus/at/priv.onet.pl) 
* harbour/include/hbcomp.h
    + added hb_compPCodeSize() and hb_compStrongType() declarations

  * harbour/include/hbpp.h
    * formatting

  * harbour/source/compiler/Makefile
  + harbour/source/compiler/hbstrong.c
  * harbour/source/compiler/hbpcode.c
    * moved strong typing code to separate file

  * harbour/source/compiler/hbpcode.c
    + added hb_compPCodeSize() function
    + added support for automatic size checking of variable size PCODEs
      in hb_compPCodeEval()

  * harbour/source/compiler/gencc.c
    * added escaping of '?' character in generated strings to
      avoid possible conflicts with trigraph sequences which
      are part of ANSI C standard
    * force .0 at the end of double numbers to avoid possible range
      conflicts in generated .c files
    * removed unnecessary HB_SYMBOL_UNUSED()

  * harbour/source/compiler/harbour.l
  * harbour/source/compiler/harbour.y
  * harbour/source/macro/macro.l
  * harbour/source/macro/macro.y
    * added #define realloc hb_xrealloc

  * harbour/source/compiler/hbdead.c
  * harbour/source/compiler/hbfix.c
  * harbour/source/compiler/hblbl.c
  * harbour/source/compiler/hbstripl.c
    * use hb_compPCodeSize() function
    * removed not longer necessary functions for checking the real size
      of variable size PCODEs

  * harbour/source/vm/hvm.c
    * fixed RT error number in hb_vmAddInt() for negative values to be
      Clipper compatible
