- Update to autoconf 2.63.
** AC_C_BIGENDIAN does not mistakenly report "universal" for some
bigendian hosts, a regression introduced with universal binary
support in 2.62.
** AC_PATH_X now includes /lib64 and /usr/lib64 in its list of default
library directories.
** AC_USE_SYSTEM_EXTENSIONS no longer conflicts with an external
AC_DEFINE([__EXTENSIONS__]). This fixes a regression introduced in
2.62 when using macros such as AC_AIX that were made obsolete in
favor of the more portable AC_USE_SYSTEM_EXTENSIONS.
** AC_CHECK_TARGET_TOOLS is usable in the non-cross-compile case.
** Newly obsolete macros
The following macro has been marked obsolete, since current porting
targets can safely assume C89 semantics that signal handlers return
void. We have no current plans to remove the macro.
AC_TYPE_SIGNAL
** The macros m4_map and m4_map_sep now ignore any list elements
consisting of just empty quotes, and m4_map_sep now expands its
separator. This fixes a regression in 2.62 when these macros were
first documented, for the sake of clients expecting the semantics
that these macros had prior to that time. The new macros m4_mapall
and m4_mapall_sep, along with extra quoting of the separator, can
be used to get the semantics that m4_map_sep had in 2.62.
** Clients of m4_expand, such as AS_HELP_STRING and AT_SETUP, can now
handle properly quoted but otherwise unbalanced parentheses (for
some macros, this fixes a regression in 2.62).
** Two new quadrigraphs have been introduced: @{:@ for (, and @:}@ for ),
allowing the output of unbalanced parentheses in more contexts.
** The following m4sugar macros are new:
m4_joinall m4_mapall m4_mapall_sep m4_reverse m4_set_add
m4_set_add_all m4_set_contains m4_set_contents m4_set_delete
m4_set_difference m4_set_dump m4_set_empty m4_set_foreach
m4_set_intersection m4_set_list m4_set_listc m4_set_remove
m4_set_size m4_set_union
** The following m4sugar macros now accept multiple arguments, as is the
case with underlying m4:
m4_defn m4_popdef m4_undefine
** The following m4sugar macros now guarantee linear scaling; they
previously had linear scaling with m4 1.6 but quadratic scaling
when using m4 1.4.x. All macros built on top of these also gain
the scaling improvements.
m4_bmatch m4_bpatsubsts m4_case m4_cond m4_do m4_dquote_elt
m4_foreach m4_join m4_list_cmp m4_map m4_map_sep m4_max
m4_min m4_shiftn
** AT_KEYWORDS once again performs expansion on its argument, such that
AT_KEYWORDS([m4_if([$1], [], [default])]) no longer complains about
the possibly unexpanded m4_if [regression introduced in 2.62].
** Config header templates `#undef UNDEFINED /* comment */' do not lead to
nested comments any more; regression introduced in 2.62.

** The macros m4_map and m4_map_sep now ignore any list elements
consisting of just empty quotes, and m4_map_sep now expands its
separator. This fixes a regression in 2.62 when these macros were
first documented, for the sake of clients expecting the semantics
that these macros had prior to that time. The new macros m4_mapall
and m4_mapall_sep, along with extra quoting of the separator, can
be used to get the semantics that m4_map_sep had in 2.62.
** Clients of m4_expand, such as AS_HELP_STRING and AT_SETUP, can now
handle properly quoted but otherwise unbalanced parentheses (for
some macros, this fixes a regression in 2.62).
** Two new quadrigraphs have been introduced: @{:@ for (, and @:}@ for ),
allowing the output of unbalanced parentheses in more contexts.
** The following m4sugar macros are new:
m4_joinall m4_mapall m4_mapall_sep m4_reverse m4_set_add
m4_set_add_all m4_set_contains m4_set_contents m4_set_delete
m4_set_difference m4_set_dump m4_set_empty m4_set_foreach
m4_set_intersection m4_set_list m4_set_listc m4_set_remove
m4_set_size m4_set_union
** The following m4sugar macros now accept multiple arguments, as is the
case with underlying m4:
m4_defn m4_popdef m4_undefine
** The following m4sugar macros now guarantee linear scaling; they
previously had linear scaling with m4 1.6 but quadratic scaling
when using m4 1.4.x. All macros built on top of these also gain
the scaling improvements.
m4_bmatch m4_bpatsubsts m4_case m4_cond m4_do m4_dquote_elt
m4_foreach m4_join m4_list_cmp m4_map m4_map_sep m4_max
m4_min m4_shiftn
** AT_KEYWORDS once again performs expansion on its argument, such that
AT_KEYWORDS([m4_if([$1], [], [default])]) no longer complains about
the possibly unexpanded m4_if [regression introduced in 2.62].
** Config header templates `#undef UNDEFINED /* comment */' do not lead to
nested comments any more; regression introduced in 2.62.
* Thu Jul 17 2008 schwab@suse.de

commit c87512b5ae11de7a98ccc8c3e42d5df6f5039fe0
Author: Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
Date: Tue Jun 17 08:42:14 2008 +0200
Fix '#undef variable /* comment */' transform in config headers.
* lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS_PREPARE): For
undefined preprocessor macros that are followed by a comment
in the header template, do not create nested comments in the
output.
* tests/torture.at (@%:@define header templates): Extend test.
* NEWS: Update.
Report by Karsten Hopp <karsten@redhat.com>.
