* harbour/source/rtl/gtgui/Makefile
* harbour/source/rtl/gtgui/gtgui.c
+ harbour/source/rtl/gtgui/gtdef.c
+ added GT version info
* modified the hack which overwrite the default GT name
Now original GTGUI is always present and only separate
file add linker bindings. It will be cleaner solution which
will allow to use REQUEST HB_GT_GUI in valid programs and
libraries.
* harbour/source/rtl/gtwin/gtwin.c
* indenting
* harbour/source/vm/garbage.c
* minor modification: use HB_GC_PTR() to take HB_GRABAGE pointer
+ added alternate code for sweep function execution - disabled by
default, maybe it will be used when we agree the sweep function
behavior
* harbour/contrib/rdd_ads/ads1.c
* BCC warnings clean-up - synced with xHarbour
* harbour/source/rtl/empty.c
* added HB_IT_SYMBOL
