BZ #15969: search locale archive again after alias expansion
|
|
|
147e83 |
|
|
|
147e83 |
If a locale alias is defined in locale.alias but not in an archive,
|
|
|
147e83 |
and the referenced locale is only present in the archive, setlocale
|
|
|
147e83 |
will fail if given the alias name. This is unintuitive. This patch
|
|
|
147e83 |
fixes it, arranging for the locale archive to be searched again after
|
|
|
147e83 |
alias expansion.
