AC_PREREQ(2.4)dnl Required Autoconf version.
dnl Do not use autoconf 2.12; it produces a configure script which produces
dnl a "internal 2K buffer" error on HPUX when run with /bin/sh.
dnl autoconf 2.10 seems like a good choice.
dnl
dnl It is possible that we should just change the above required version
dnl to 2.10; it seems like everyone is using 2.10 anyway, and there is
dnl at least some sentiment that we should be using a version which has
dnl --bindir (and correspondingly, using @bindir@ and friends in our
dnl Makefile.in files. I'm not sure exactly what version of autoconf
dnl introduced --bindir but I know 2.10 has it.
