3            Based on a patch from Marius Vollmer <mvo@zagadka.ping.de>:
4            * NEWS: updated.
5            * ltdl.m4 (AC_LIB_LTDL): Check for unistd.h.
6            * ltdl.c: Include unistd.h if it exists.
7            (LTDL_SEARCHPATH_VAR): Macro to prevent hardcoding
8            "LTDL_LIBRARY_PATH".
9            (LTDL_ARCHIVE_EXT): Macro to prevent hardcoding ".la".
10            (archive_ext): Have only one copy of ".la" in the readonly
11            segment of the compiled library.
12            (find_handle_callback): Don't bother trying to dlopen the file if
13            it doesn't exist.
14            (find_handle): Don't bother searching for files if no search_path
15            was supplied.
16            (file_not_found): A new function to determine whether the last
17            error was due to a file not found condition.
18            (try_dlopen): Renamed from lt_dlopen() and changed to have the
19            same footprint as tryall_dlopen.  This involved a minor rewrite of
20            much of the internals of this function.
21            (lt_dlopen): A new function wrapped arounf try_dlopen().
22            (lt_dlopenext): If a file already has a suitable extension, don't
23            bother adding additional extensions and trying to open those.
24            Tidy up the rest of the code to prevent continued searching with
25            an eventual FILE_NOT_FOUND when a genuine failure earlier in the
26            search process could be legitimately reported.
27    
28          * demo/Makefile.am (helldl$(EXEEXT)): Automake-1.5 made me change          * demo/Makefile.am (helldl$(EXEEXT)): Automake-1.5 made me change
29          this from just `helldl'.          this from just `helldl'.
