+ getopt.m4sh generated libtool option parser, and XSI improvements.
+ * libltdl/m4/libtool.m4 (_LT_PROG_XSI_SHELLFNS): Moved portable
+ shell versions of various utility functions from here...
+ * libltdl/config/getopt.m4sh (func_split_long_opt): ...to here...
+ * libltdl/config/general.m4sh (func_dirname, func_basename)
+ (func_dirname_and_basename, func_strip_name): ...here...
+ * libltdl/config/ltmain.m4sh (func_append, func_arith, func_len)
+ (func_lo2o, func_xform): ...and here.
+ * libltdl/config/libtool.m4 (_LT_PROG_XSI_REPLACE): New macro that
+ expands into a sed command for replacing the contents of a
+ suitably decorated shell function with an alternate XSI
+ implementation.
+ (_LT_PROG_XSI_SHELLFNS): Use it to replace the portable shell
+ versions of the functions above with equivalent XSI
+ implementations that avoid unnecessary forks if the host shell
+ supports that.
+ * libltdl/config/ltmain.m4sh: Replace hand written shell code
+ with a call to M4SH_GETOPTS. Rename some option variables in
+ the client code to match the generated option parser settings.
+ * libltdl/config/general.m4sh (func_echo, func_error)
+ (func_warning): Use $opt_mode instead of obsoleted $mode in
+ message leader.
+ * libltdl/config/getopt.m4sh (m4_version_prereq): This file
+ requires m4sugar.m4 from Autoconf-2.61 or newer.
