Deal with Autoconf 2.62's semantic change in m4_append.
|
||
|
|
* ltsugar.m4 (lt_append): Replace broken versions of
|
||
|
|
m4_append.
|
||
|
|
(lt_if_append_uniq): Don't require separator to be overquoted, and
|
||
|
|
avoid broken m4_append.
|
||
|
|
(lt_dict_add): Fix typo.
|
||
|
|
* libtool.m4 (_LT_DECL): Don't overquote separator.
