tested on win32/64 to pass the tests when enabled - libtcc.c : let tcc define __leading_underscore if enabled tcc_add_symbol() : add _ automatically - tccelf.c : remove tcc_get_symbol_err(), find_c_sym() currently symbol length is limited to 256 in several places, so we can use a fixed local buffer for now as well. - win32/lib/crtinit.c : new file for init/fini - lib/*.S, tests7* : use __leading_underscore - bt-log.c: this file wont work relibaly if compiled with gcc
