CVS autoconf, otherwise pdksh chokes on some nested escaped quotes from libtool.m4. Using CVS autoconf protects configure from non-bourne compatible shells in the same way this changeset protects libtool and libtoolize: * libtoolize.in: Include latest CVS autoconf AS_SHELL_SANITIZE expansion to make various shells fully bourne compatible. * ltmain.in: Ditto. * m4/libtool.m4 (AC_PATH_TOOL_PREFIX): Remove spurious quotes, the RHS of = assignment is not IFS split. (_LT_LANG_CXX_CONFIG): Ditto. (AC_LIBTOOL_POSTDEP_PREDEP): Ditto.
