autoconf 2.60 runs into an endless loop

configure.ac contains a check which fails if any other version of autoconf than 2.59 is used: dnl Due to a dependence on the implementation of certain internal autoconf dnl macros, die if any version other than 2.59 is used. AC_PREREQ(2.59)dnl m4_if(m4_version_compare(m4_defn([m4_PACKAGE_VERSION]), [2.59]), 1, [m4_fatal([This script can only be generated with autoconf 2.59])], [])dnl To try whether using autoconf 2.60 works, I removed that check and called autoconf --force Unfortunately, m4 runs into an endless loop then. I have no idea yet why. On an SXEmacs mailing list I found a patch related to autoconf 2.60: http://www.sxemacs.org/list-archives/html/sxemacs-patches/2006-03/msg0004... but this seems to fix an additional, it doesn't help for the endless loop problem. Do you have any ideas what the problem with autoconf 2.60 is? -- Mike FABIAN <mfabian(a)suse.de&gt; http://www.suse.de/~mfabian 睡眠不足はいい仕事の敵だ。
