out ac_cv_global_symbol_to_cdecl inside the loop, incase we
need to go around again and try with underscore prefix.
(_LT_AC_TRY_DLOPEN_SELF): On some hosts (cygwin for instance)
self dlclosing unloads the main program and causes a SIGSEGV. So
don't do it for now.
way. This should fix it some:
* libtool.m4 (extract_expsyms_cmds): There is a quoting problem
with autoconf-2.13 that prevents [$]0 from expanding. Use shell
quotes instead to delay eval of $0.
(impgen.c) The '# ' sequence stripped by sed works again.
from here...
(AC_LTDL_DLOPEN_SELF): ...to here.
(_LTDL_AC_CHECK_DLFCN): Factor out repeated code for dlfcn.h
(_LT_AC_TRY_DLOPEN_SELF): Factor out repeated code for
checking dlopen status.
* ltdl.m4 (AC_LIB_LTDL): Use _LTDL_AC_CHECK_DLFCN.
dlopen compile time checking. Use _LTDL_AC_CHECK_DLFCN.
(AC_LTDL_DLSYM_USCORE): Use _LTDL_AC_TRY_DLOPEN_SELF.
Quote all the macro names when defined.
Some minor formatting changes.
(AM_PROG_LIBTOOL, AM_ENABLE_SHARED, AM_ENABLE_STATIC)
(AM_DISABLE_SHARED, AM_DISABLE_STATIC, AM_PROG_LD, AM_PROG_NM):
Don't use indir when useless. Don't add trailing `dnl' either.
* demo/configure.in: Revert to the `libtool --features' test.
* Makefile.am (libtool): This needs to rerun configure now that
libtool is generated entirely by AC_PROG_LIBTOOL again.
(ltconfig): Removed.
(ltmain.sh): Is now regenerated when ltmain.in changes.
* libtool.m4 (_LT_AC_LTCONFIG_HACK): Now does all of the work for
generating libtool immediately in configure.in, rather than
deferring part of the creation until config.status runs.
necessary.
* Makefile.am (libtool): Reworked rule for regeneration of libtool,
now that it is built entirely withing config.status.
(libtoolize): Tidied for orthogonality with the other generation
rules.
(ltconfig): This is now generated by AC_PROG_LIBTOOL, called from
make by running config.status --recheck.
(ltmain.sh): Moved primary generation of this file into here...
* configure.in (AC_OUTPUT): ...instead of here.
* libtool.m4 (AC_OUTPUT_COMMANDS): Write the config to ltconfig
where it can be reused, rather than directly to libtool.
* demo/configure.in: libtool is no longer present immediately
after AC_LIBTOOL_M4 has completed, so the tests now grep through
ltconfig instead -- which *will* be present.
macro.
(AC_LTDL_SYMBOL_USCORE): ditto.
(AC_LTDL_GLOBAL_SYMBOL_PIPE): Removed, since it is a duplicate
of...
* libtool.m4 (AC_LIBTOOL_SYS_GLOBAL_SYMBOL_PIPE): ...this new
macro, extracted from _LT_AC_LTCONFIG_HACK.
* libtool.m4 (pw32): Initial support for pw32, assuming that
libtool's behaviour in this environment is identical to under
cygwin.
* ltmain.in (pw32): ditto.
* NEWS: Updated.
bug in Autoconf-2.13 AC_REQUIRE implementation which inserted
some of the expanded tests too early in the generaated configure.
(_AC_PROG_LIBTOOL): renamed to AC_PROG_LIBTOOL, and defines
itself to an empty expansion to prevent multiple expansions.
configure.in (AC_LIBTOOL_SETUP): Replaced by a call to
AC_PROG_LIBTOOL now that the AC_REQUIRE bug has been worked
around.
from ltconfig, so that ltmain.sh and then libtool are
generated at configure time.
* Makefile.am: Don't generate ltmain.sh or ltconfig anymore.
* bootstrap: ltconfig is no more!
* configure.in: Call AC_PROG_LIBTOOL directly.
(AC_OUTPUT): Generate tmain.sh.
* libtool.m4: Don't build an argument list for ltconfig.
(_LT_AC_LTCONFIG_HACK): Refactoring of the former contents of
ltconfig.in to take advantage of the m4 macros from autoconf.
* ltmain.in: Don't do a version check against ltconfig.
* tests/assign.test: Remove reference to ltconfig.
* tests/hardcode.test: ditto.
* tests/sh.test: ditto.
at the top ofltconfig.in is ugly, but will go away when the rest
of ltconfig is migrated.
* Makefile.am (libtool): Pass the value of $ECHO to ltconfig as
an environment variable.
* libtool.m4 (_LT_AC_PROG_ECHO_BACKSLASH): Quote the ECHO value
correctly so that it inserts the correct code into configure.in
suitably quoted for M4 expansion. This code needs to be near
the top of configure.in as it calls itself recursively, so I
am using AC_DIVERSION_NOTICE (or simply NOTICE on CVS
Autoconf). The value of ECHO is also substitued into the
Makefile to be used when Make calls ltconfig to generate
libtool, so another layer of quotation is required for the
Makefile.
(AC_LIBTOOL_SETUP): Use it.
* ltconfig.in: Accept a value for ECHO from the environment, and
carefully substitue for $0 if it is present in the ECHO value.
Because ECHO was quoted for Make, when ltconfig is called by
configure, it is overquoted, and one layer of quotes must be
stripped.
interdependent libraries (e.g. -la -lb -la),
this requires adding deplibs in reverse order

* libtool.m4: recognize powerpc*linux* (reported by
Dirk A. Mueller <dmuell@gmx.net>)
AC_SUBST, `AC_SUBST(FILE)' can never work. Use MAGIC as the
holder of the command to run in file_magic_cmd instead.
* ltconfig.in: s/FILE/MAGIC/g.
* libtool.m4 (AC_PROG_LIBTOOL): set MAGIC in the environment when
calling ltconfig.
(AC_PATH_MAGIC): renamed from AC_PATH_FILE.
(AC_PATH_TOOL_PREFIX): s/FILE/MAGIC/g. Also set file_magic_cmd
to '${MAGIC}' so that make can grok it.

into libraries
* ltmain.in: minor cleanups, we don't need to add user-specified
rpaths to compile_rpath, finalize_rpath is sufficient
* ltconfig.in: transform linux* -> *linux-gnu* _after_ host_os has
been set! (reported by Bruno Haible <haible@ilog.fr>)
* configure.in: AC_SUBST reload_flag, deplibs_check_method
