2018-08-27  Karl Berry  <karl@freefriends.org>

	* kpse-potrace-flags.m4: remove file, again bundled with dvisvgm.
	* kpse-pkgs.m4 (KPSE_ALL_SYSTEM_FLAGS),
	(kpse_libs_pkgs): no more potrace.

2018-02-09  Karl Berry  <karl@freefriends.org>

	* kpse-pkgs.m4 (kpse_utils_pkgs): add axodraw2.

2018-01-08  Karl Berry  <karl@freefriends.org>

	* ax_cxx_compile_stdcxx.m4: move from dvisvgm; original from
	https://www.gnu.org/software/autoconf-archive/ax_cxx_compile_stdcxx.html#ax_cxx_compile_stdcxx

2017-12-08  Norbert Preining  <preining@logic.at>

	* kpse-icu-flags.m4 (KPSE_ICU_SYSTEM_FLAGS): also check for PKG_CONFIG.
	(KPSE_ICU_SYSTEM_FLAGS): try pkg-config if icu-config fails.

2017-12-02  Karl Berry  <karl@freefriends.org>

	* kpse-visibility.m4 (KPSE_COMPILER_VISIBILITY): write debug line.
	(_KPSE_VISIBILITY_FLAGS): only restore from kpse_save_flags
	if we set it, i.e., if not using the cached value. (Otherwise,
	e.g., in libpng, we can end up overriding the user-set CFLAGS with
	the empty string.)

2017-11-02  Karl Berry  <karl@freefriends.org>

	* kpse-setup.m4 (_KPSE_RECURSE): revert previous change,
	as (1) it causes configure to fail in the cut-down pdftex source tree,
	and (2) for 2018, more packages (icu, poppler, ...) are going to
	require C++11, so we can't hack around it again. So not worth
	spending more time refining.
	Also, write debug line to >&AS_MESSAGE_LOG_FD (config.log).
	reautoconf.

2017-02-17  Karl Berry  <karl@freefriends.org>

	* kpse-setup.m4 (_KPSE_RECURSE): do not add a package to
	CONF_SUBDIRS if --disable-PKG was given. Thus, the directory for a
	disabled package will no longer be descended into at all, as if it
	were nonexistent. This way, if a package's configure causes
	problems on some systems (like dvisvgm v2's new requirement for
	C++11), --disable-PKG can be given and work can go on.
