+ HB_SYMBOL_UNUSED() added for .prg code. It can suppress unused
var warnings where applicable. The code won't generate any final
pcodes, so it won't cause overhead. The only current downside
is that it cannot be used inside codeblocks.
! Fixed a number (>200) of declared but unused variable /w2 error.
All parts were scanned and fixed (except contrib).
Note that there are several false "unreachable code" warnings,
and there are still quite a few unused var warnings inside
codeblocks. After fixing these /w2 switch could be added to
the standard build process to maintain code quality.
