* include/hbdefs.h
+ Added HB_ISALNUM() macro.
* include/hbpp.h
* include/hbapicdp.h
* contrib/hbct/pos1.c
* contrib/hbct/ascpos.c
* contrib/xhb/hbxml.c
* contrib/hbtip/utils.c
* contrib/examples/pp/hbppcore.c
* source/vm/itemapi.c
* source/vm/memvars.c
* source/vm/set.c
* source/vm/classes.c
* source/debug/dbgentry.c
* source/common/hbstr.c

* source/rtl/hbffind.c
* source/rdd/workarea.c
* source/compiler/hbmain.c
* source/compiler/harbour.yyc
* source/compiler/harbour.y
* Replaced:
isdigit() -> HB_ISDIGIT()
isalpha() -> HB_ISALPHA()
isalnum() -> HB_ISALNUM()
isupper() -> HB_ISUPPER()
islower() -> HB_ISLOWER()
tolower() -> HB_TOLOWER()
toupper() -> HB_TOUPPER()
* source/rtl/natmsg.c
! Fixed to use CP sensitive case conversion in
__NATISNEGATIVE() and __NATISAFFIRM().
* source/rtl/is.c
! Fixed typo in recently added hb_charIsUpper()/hb_charIsLower()
functions.
; TODO: Remove DJGPP to*() hack.
; TODO: Replace HB_PP_UPPER(), HB_PP_ISDIGIT() with equivalent
new macros.
; TOFIX: Some of the above macros should better be replaced
by CP sensitive versions. F.e. the one in hbtip.
; TOFIX: Remove remaining #include <ctype.h> lines.
