dnl Fix Autoconf-2.59 AC_CONFIG_SUBDIRS whitespace mangling,
dnl by overriding the broken internal Autoconf macro with a
dnl backport of the 2.60 fix.
dnl
dnl This file should be a no-op for Autoconf versions != 2.59.
dnl It can be removed once the complete tree has moved to a
dnl newer Autoconf version.

dnl m4_PACKAGE_VERSION is an undocumented Autoconf macro.
dnl We use it because this fix is intended for 2.59 only.
dnl A feature test for the broken AC_CONFIG_SUBDIRS instead
dnl would be better but is tricky.
dnl
dnl Use ifdef/ifelse over m4_ifdef/m4_ifelse to be clean for 2.13.
dnl Redefine AC_CONFIG_SUBDIRS so aclocal pulls in this file
dnl when needed.

ifdef([m4_PACKAGE_VERSION],
[ifelse(m4_PACKAGE_VERSION, [2.59], [

dnl Redefine AC_CONFIG_SUBDIRS so this file is picked up if needed.
