+ source/debug/dbgbrwsr.prg
+ The new file with TDbgBrowser class which inherits
from TBrowse
* hrbdll.bc
* hrbdll.vc
* makefile.bc
* makefile.nt
* makefile.vc
* source/debug/Makefile
+ added the reference to dbgbrwsr.prg
* source/debug/dbgmenu.prg
+ added "Run at Startup' option
* source/debug/dbgtwin.prg
* source/debug/debugger.prg
* source/debug/tbrwtext.prg
+ added "Run at Startup' option - if it is enabled then
the debugged application runs until ALTD() is called or
Alt+D keys pressed (Clipper compatibility - the default
option). If it is disabled the the debugger shows up at
the first code line with the debug info.
This setting is stored in the initialization file
(init.cld) as 'Options NoRunAtStartup'.
* fixed more display/refreshing issues
* fixed quiting the debugger
* source/rtl/alert.prg
* fixed bug with messages longer then 60 bytes
* source/vm/hvm.c
* hb_vmDebugEndProc() is called before the eval stack
is cleaned - this allows to handle INIT/EXIT procedures
correctly
