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.
