-Subject: [PATCH] libidn: fix build with automake 1.12
-
-Upstream-Status: Inappropriate
-
-automake 1.12.x has deprecated AM_PROG_MKDIR_P , and throws a warning for that,
-and the warnings are treated as errors because of the -Werror parameter.
-
-These AM_PROG_MKDIR_P are coming from gettext, and the latest gettext code has not
-eliminated these deprecated macros yet. So disable the treatment of warnings
-as errors until gettext is updated to remove the deprecated macros.
