* harbour/include/hbexprb.c

operation and because some valid Clipper code needs it then
I disabled error message.
* harbour/common.mak
* harbour/source/rtl/Makefile
+ harbour/source/rtl/einstvar.prg
+ added undocumented CA-Cl*pper function _eInstVar() used to validate
variable type in assign messages.
* harbour/include/hbapi.h
* harbour/source/vm/arrays.c
* changed 'char *' to 'const char *' in hb_arraySetC() and hb_arraySetCL()
* harbour/source/rdd/dbcmd.c
* cleaned DBSKIPPER() code
* harbour/source/rtl/browdb.prg
* use written in C DBSKIPPER() function instead of static .prg Skipped()
when HB_COMPAT_XPP macro is enabled
* harbour/source/rtl/browse.prg
! fixes in BROWSE() function:
! displaying box characters
