1 dnl Process this file with autoconf to produce a configure script.
3 dnl There are two types of comments in this file.
4 dnl Comments that refer to Autoconf macros begin with "dnl", and m4
5 dnl discards them. Other comments begin with "#", and they get copied
6 dnl to the configure script, hopefully making it easier to read.
8 dnl Autoconf 2.13 generates an incomplete config.h.in; see ELinks bug 936.
9 dnl Autoconf 2.59 is installed in the computer that generates our nightly
10 dnl snapshots, so we need to be compatible with that.

251 # the executable to its dynamic symbol table. ELinks uses this for
254 # 1. If ELinks detects a bug, it can try to display a backtrace by
255 # calling backtrace_symbols_fd() in the GNU libc. The glibc-2.3.6
256 # manual states users of GNU ld must pass -rdynamic to make the
257 # symbols available to the program.
259 # 2. It would eventually be nice to dynamically load shared
260 # libraries as plugins (bug 73). The plugins must be able to
261 # call ELinks functions. This can be implemented either by
262 # registering all callable functions in ELinks-specific data
263 # structures, or by letting the dynamic linker handle them.
264 # The latter way requires something equivalent to -rdynamic.
266 # Because backtraces are not needed for correct operation, and bug
267 # 73 is not yet being fixed, the configure script and makefiles
268 # should not complain to the user if they find that -rdynamic does
269 # not work. Besides, it was reported at elinks-users on 2006-09-12
