Hello Alexandre, thank you for your prompt reaction. The patch removes the line:
> -## Location of top build directory relative to this one. > -top_builddir = %TOPDIR% because top_builddir is now substituted by autoconf. The question is: shouldn't the automake "variable" TOPDIR be removed? When I grep the CVS version, I see only one usage of TOPDIR, in ./lib/am/libtool.am, and though I don't understand the file, I guess that it could be perhaps replaced by TOPDIR_P there. Thank you for any explanation about this naive suggestion. Stepan
