* harbour/tests/langmsg.prg
* harbour/utils/hbpptest/pp_test.prg
* harbour/utils/hbpptest/pretest.prg
* harbour/samples/pe/license.txt

* harbour/source/compiler/hbcomp.c
* harbour/source/compiler/hbident.c
* harbour/source/compiler/hbpcode.c
* harbour/source/compiler/ppcomp.c
* separated HB_COMP and HB_MACRO definitions and added HB_COMMON
structure used when HB_COMMON_SUPPORT macro is set
* hide HB_MACRO internal definitions in hbapi.h when HB_MACRO_SUPPORT
is not set
These modifications should help in future compiler and macro compiler
integration into single binary.
+ added clipper compatible error message in unclosed structures
In general we should cleanup rules to make error reporting more
user friendly and Clipper compatible
% eliminated unnecessary allocations
+ added int mode member to common part of HB_COMP and HB_MACRO
structure. It's initialized to HB_MODE_MACRO or HB_MODE_COMPILER
+ add TOFIX note about memory leaks in cParamTypes and pParamClasses
members of COMDECLARED structure. It's a part of unfinished strong
typing code. I do not know what Ryszard plan to do with it so I'm
leaving it as is. The part of strong typing which were operating
on emulated HVM stack has been removed.
* removed static variables from genjava.c. Also gencli.c and genobj32.c
should be fixed but this will not make this code working so I haven't
touched it.
* changed 3-rd parameter of hb_compIdentifierNew() from BOOL to int.
Now it can have the following values: HB_IDENT_STATIC, HB_IDENT_FREE,
HB_IDENT_COPY. This modification will allow in the future using common
for static and dynamic symbol hash table without additional source code
changes. I also plan to use identifier hash table in PP the reduce
number of memory allocations and speed-up preprocessing by using
second level hashing for hash keys.
* harbour/source/common/expropt1.c
* harbour/source/common/expropt2.c
* changed HB_MACRO_SUPPORT to HB_COMMON_SUPPORT to automatically detect
possible conflicts between compiler and macro compiler
! removed first detected conflict which existed for long time
+ added hb_compExprMacroAsAlias() function to convert HB_ET_VARIABLE
expression to HB_ET_ALIAS.
* harbour/source/macro/macro.y
! fixed using prefix¯o-> and ¯o.sufix-> when macro cannot be
substituted by compiler, f.e.:
M->v := NIL
x := "&v.1->fld"
M->v := "v"
M->v1:= "data"
? &x
! fixed memory leak in macro substituted expression compilation
* harbour/source/vm/macro.c
! fixed initialization of some HB_MACRO members
! fixed value returned for type("&V->F") when alias does not exist
- removed not longer used hb_comp_bShortCuts global variable
