You don't mention your platform, but there is a known incompatibility of Autoconf 2.54 with traditional Unix make in that area. Please see:
http://mail.gnu.org/pipermail/autoconf-patches/2002-September/008689.html http://mail.gnu.org/pipermail/autoconf-patches/2002-September/008692.html This problem should be fixed in the next version of Autoconf. To work around the problem in the meantime, you can use GNU make (e.g., "gmake" on Solaris 8 or later).
