+Subject: [PATCH] Fix msginit compatibility with gettext >= 1.0.
+
+gettext 1.0 changed msginit behavior: when the output PO file already
+exists, msginit now merges into it like msgmerge instead of failing
+with an error.  This breaks po4a because it passes an empty PO file as
+the output target; msginit merges into the empty file and produces a PO
+with stripped headers and corrupted content.
+
+Remove the output file before calling msginit when it exists and is
+empty, so that msginit always creates a fresh PO file with proper
+headers.
+
+* po4a: Before calling msginit, unlink the output file if it exists
+and is empty.
