how "newer"?
2.59?

I don't understand this code (why is there a line break in the m4_map_args_w 
invocation?)
but this patch the cvs head:

without the --trace arguments, I get this:

cd modules/berkeley-db && autoconf --include=/home/sds/src/clisp/current/src
configure:1981: error: possibly undefined macro: m4_map_args_w
      If this token and others are legitimate, please use m4_pattern_allow.
      See the Autoconf documentation.
make: *** [modules/berkeley-db/configure] Error 1

on processing the first configure.in which calls CL_CLISP.


Thanks!
