+ Port to hosts whose 'sort' and 'tail' implementations
+ treat operands with leading '+' as file names, as POSIX
+ has required since 2001. However, make sure the code still
+ works on pre-POSIX hosts.
+ * ltmain.sh: Don't assume "sort +2" is equivalent to
+ "sort -k 3", since POSIX 1003.1-2001 no longer requires this.
