m4/ltsugar.m4, m4/ltversion.m4, m4/lt~obsolete.m4: RMS says,
'I think the [license of autoconf macro files] should be:
# This file is free software; the Free Software Foundation
# gives unlimited permission to copy and/or distribute it,
# with or without modifications, as long as this notice is
# preserved.'.
(EXTRA_DIST): Remove m4 macro files; they are automatically
added by automake.
(pkgmacrodir): Where to install libtool macro files.
(pkgmacro_DATA): List installable libtool macro files.
(install-data-local): Remove previous versions of ltdl.m4 and
libtool.m4 from their old location.
* libtoolize.in: Use new pkgmacrodir installed macros when
libtoolizing a project. Treat libtool.m4 and ltdl.m4 specially,
and func_serial_update() any other files from pkgmacrodir.
(pkgmacrodir): Where to find installed libtool macro files.
(aclocaldir): Removed.
(func_copy_all_files): Add an optional callback parameter to
control how files are copied. If the callback is passed, don't
tell it whether it can copy or not.
(func_serial): Exchange parameters and make macro_regex optional,
so that this function can be used to extract serial numbers from
files with the traditional /^# serial [1-9][0-9]*$/ syntax.
Changed all callers.
(func_serial_update): Make macro_regex optional last parameter, so
that this function can be used as a callback for
func_copy_all_files(). Changed all callers.
* m4/ltsugar.m4: Add a serial number.
libtool via config.status. The old way involved manually
synchronising disparate bits of shell code in several macros, to
quote a copy of a shell variable, put that in config.status, maybe
add it to some quotation loops to prevent early expansion, and
then add a block to _LT_CONFIG_COMMANDS to bring it into the
libtool script. The new way is to mark shell variables for
propogation using _LT_DECL for language independent variables, or
_LT_TAGDECL for those that need to be propogated in several
language flavours. The marking can be done in the macro that
probes the variables, and this new m4 machinery takes care of
synchronising all the other bits of code at autoconf time:
* m4/ltsugar.m4: New file. Macros that are useful outside the
context of libtool. Initially, contains some generalised list
management macros, and the scaffolding for dictionary type data
storage and retrieval.
* Makefile.am (aclocal_macros): Install ltsugar.m4.
* m4/libtool.m4 (_LT_DECL): Mark a shell variable for export to
the libtool script, along with a comment, and hints for quoting
and renaming.
(_LT_TAGDECL): Similarly mark a tagged shell variable for export
in each tag.
(lt_decl_tag_varnames, lt_decl_quote_varnames)
(lt_decl_dquote_varnames, lt_decl_varnames_tagged)
(lt_decl_all_varnames): New utility macros for managing lists of
shell variable names from _LT_DECL and _LT_TAGDECL.
(_LT_CONFIG_STATUS_DECLARATIONS, _LT_CONFIG_STATUS_DECLARE):
Expand to correctly quoted variable declarations in config.status
from all marked shell variables.
(_LT_LIBTOOL_DECLARE): Expand to commented and quoted variable
declaration for libtool tag section.
(_LT_LIBTOOL_CONFIG_VARS, _LT_LIBTOOL_TAG_VARS): Pass all marked
variables to _LT_LIBTOOL_DECLARE.
(_LT_CONFIG_COMMANDS): Use _LT_CONFIG_STATUS_DECLARATIONS and
friends to generate all the variable passing shell code for
config.status, to get marked variables from libtool.m4 into
libtool itself eventually.
(AC_LIBTOOL_CONFIG): Generate marked variable code for libtool tag
configuration. Changed all client macros to mark variables
suitably rather than the hand pasting that was necessary
previously.
(AC_PROG_SED): Renamed from LT_AC_PROG_SED.
(LT_AC_PROG_SED): Wrap AC_PROG_SED, and mark shell variables for
propogation to the libtool script.
