ELinks uses this for dnl two purposes: dnl dnl 1. If ELinks detects a bug, it can try to display a backtrace by dnl calling backtrace_symbols_fd() in the GNU libc. The glibc-2.3.6 dnl manual states users of GNU ld must pass -rdynamic to make the dnl symbols available to the program. dnl dnl 2. It would eventually be nice to dynamically load shared dnl libraries as plugins (bug 73). The plugins must be able to dnl call ELinks functions. This can be implemented either by dnl registering all callable functions in ELinks-specific data dnl structures, or by letting the dynamic linker handle them. dnl The latter way requires something equivalent to -rdynamic. dnl dnl Because backtraces are not needed for correct operation, and bug dnl 73 is not yet being fixed, the configure script and makefiles dnl should not complain to the user if they find that -rdynamic does dnl not work. Besides, it was reported at elinks-users on 2006-09-12 dnl that gcc-3.4.2 with "ld: Software Generation Utilities - Solaris dnl Link Editors: 5.8-1.284" on Sun Solaris 8 Sparc does not support dnl -rdynamic but does something equivalent automatically. (This was dnl tested with "nm -D elinks | grep redraw_from_window".) dnl dnl FIXME: This check doesn't work. Something to do with the compiler dnl happily ignoring it and stderr not being checked for error messages.
