(sysdep_dynl_link): Added `flags' argument. (kw_global, sym_global): New. (scm_dynamic_link): Handle keyword arguments. Pass suitable flags to sysdep_dynl_link. * dynl-dl.c (sysdep_dynl_link): Handle new `flags' argument by conditrionally adding RTLD_GLOBAL to DLOPEN_MODES. * dynl-shl.c (sysdep_dynl_link): Add and ignore new flags argument. * dynl-dld.c (sysdep_dynl_link): Add and ignore new flags argument. * dynl.h (scm_dynamic_link): Added rest argument. * dynl.c (sysdep_dynl_unlink, sysdep_dynl_func): Use const qualifier for char* argument, to match prototypes. Thanks to Mark Elbrecht.
