+Subject: [PATCH 1/1] Silence uninitialized warning on ehdr_start_save
+
+Older GCC, like 4.1/4.2, will issue an uninitialized warning on
+ehdr_start_save.  This patch silences by using
+
+struct bfd_link_hash_entry ehdr_start_save = ehdr_start_save;
+
+        * emultempl/elf32.em (gld${EMULATION_NAME}_before_allocation):
+        Silence uninitialized warning on ehdr_start_save with older
+        GCC.
+
+Upstream-Status: Backport
