* makefile.bc
* makefile.nt
* makefile.vc
* source/rtl/Makefile
*added a reference to rtl/altd.prg
* source/common/hbffind.c

+added missing support for @¯o and @M->memvar
+added new pcode HB_MACROPUSHREF (all sources have to be
recompiled)
* source/debug/dbgtwin.prg
* source/debug/debugger.prg
*fixed procedures callstack when modules with/without debug info
are linked together
*fixed the debugger activation when ALTD() is used in
a module with no debug info (the debugger shows up
on the first line with debug info after the ALTD()
is called)
NOTICE:
Some compilers may require that the debug library has to
be specified as an object file in order to get the
debugger linked in.
