dnl Fix Autoconf-2.59 bugs: by overriding broken internal
dnl Autoconf macros with backports of the 2.60+ fix.
dnl - AC_CONFIG_SUBDIRS whitespace mangling,
dnl - more lenient precious variable checks
dnl - better configure error message
dnl - reliance on non-Posix m4wrap (M4 1.6 or newer implement FIFO)
dnl
dnl The override bits of this file should be a no-op for the newest
dnl Autoconf version, which means they can be removed once the complete
dnl tree has moved to a new enough Autoconf version.
dnl
dnl The _GCC_AUTOCONF_VERSION_TEST ensures that exactly the desired
dnl Autoconf version is used. It should be kept for consistency.
dnl Provide m4_copy_force and m4_rename_force for old Autoconf versions.

[m4_ifdef([$2], [m4_undefine([$2])])m4_rename($@)])])
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.
