+        GCC 3.3 (sparc) no longer puts "int foo = 0;" into data; it
+        puts it into BSS instead, at least on Solaris 8 and 9.
+        This is a valid optimization, and it may occur on other platforms,
+        so Emacs should not assume that initializing a static variable to
+        zero puts it into data.
+        * alloc.c (pure, staticvec):
+        Initialize these arrays to nonzero, so that they're not
+        put into BSS by that optimization.

         * s/netbsd.h (START_FILES_1, END_FILES_1): Always define them.
