* libltdl/Makefile.am (CFLAGS): ditto * libltdl/configure.in: check for memory.h, rindex() and dlpreopening. Fixed NEED_USCORE caching policy. * libltdl/ltdl.h (lt_dlsym): make the name argument const * libltdl/ltdl.c (types): new variable: head of list of available dlopening mechanisms (lt_dltype_t): interface of a dlopening mechanism, with pointers to functions for init, exit, open, close and sym (lt_dlhandle_t): added pointer to interface type (strdup): don't name it strdup; it can be troublesome (strrchr): ditto; use rindex if available (LIBTOOL_STATIC): check HAVE_DLPREOPEN instead, and move to the end of the file, so that it becomes the header of the list (all): renamed all interface-implementation functions, to avoid name clashes, and created lt_dltype_t nodes for all of them (lt_dlinit): initialize all available interfaces; remove those that fail from the list. Return failure only if no interfaces could be initialized. (lt_dlexit): return number of failures (tryall_dlopen): try to open the library with all available interfaces (lt_dlopen): use tryall_dlopen; increased size of fixed buffers. We should probably make these bound-checked or dynamically allocated for the final release! Fix bug when filename did not contain slashes; should we check for `\\' too? Try old_library if everything else fails. (lt_dlclose): use the interface type for closing (lt_dlsym): make `symbol' const, use interface type for looking up * mdemo/Makefile.am: moved mdemo/modules/* back into mdemo (SUBDIRS): removed (libfoo2_la_LDFLAGS): added -static; nice test. However, since it causes -lm to linked into hell*, it causes tests that should fail to pass (noinst_HEADERS): no need to install foo.h * mdemo/configure.in: remove modules/Makefile tests/mdemo-exec.test: updated accordingly
