The +dnl result: the search_path_spec is a single word still containing the +dnl ":" separators. +dnl +dnl This macro fixes the situation: when we see the libtool PATH_SEP to +dnl be ":" and search_path_spec to contain ":" characters, then these +dnl are replaced with spaces to let the resulting string work as a +dnl for-loop argument in libtool scripts that resolve -no-undefined +dnl libraries. +dnl +dnl Later libtool generations have fixed the situation with using +dnl $PATH_SEPARATOR in the first place as the original path delimiter +dnl that will be scanned for and replaced into spaces. +dnl +dnl @category Misc +dnl @author Guido U.
