* harbour/makefile.bc
* harbour/config/c.cf
* changed default settings to not use bison for generation new
grammar files. Now developers who will want to update our
grammar definition files for compiler and macro compiler
should set environment variable HB_REBUILD_PARSER=yes
to force preprocessing new rules by bison and should
remember to update before committing modifications in *.y
file(s) corresponding *.yy[ch] files by copping the new
ones generated by parser.
! fixed typo in makefile.bc - instead of $(HARBOUR_DIR)\macro.yyc
should be $(MACRO_DIR)\macro.yyc
