* harbour/include/hbinit.h
* eliminated from ASM code used in HB_INITSEG_STARTUP direct references
to public functions - it resolves the problem with non relocatable
code breaking Harbour shared library.
TODO: find portable method to mark function as used for C compiler
without using any public symbols (functions or variables)
which may cause conflicts between modules.
Compilers like modern GCC versions are clever enough to detect
cyclic references (only compile time warnings are pacified in
such case) and they strip even group of functions it they are
not accessed externally.
