collect2.c (dump_file): Don't call cplus_demangle if HAVE_LD_DEMANGLE is defined.
2004-07-07 H.J. Lu <hongjiu.lu@intel.com>
* collect2.c (dump_file): Don't call cplus_demangle if
HAVE_LD_DEMANGLE is defined.
(main): Pass "--demangle" to ld if no_demangle is not 0 and
HAVE_LD_DEMANGLE is defined. Don't set current_demangling_style
if HAVE_LD_DEMANGLE is defined.
* configure.ac (--with-demangler-in-ld): Added
(HAVE_LD_DEMANGLE): Define if ld supports --demangle when
--with-demangler-in-ld is used.
* config.in: Regenerated.
* configure: Likewise.
