+Subject: [patch] #pragma pack vs. STRUCTURE_SIZE_BOUNDARY
+Date: Sun, 22 Oct 2006 16:32:31 +0100
+
+Currently STRUCTURE_SIZE_BOUNDARY is obeyed even when
+#pragma pack(1) is in effect. By contrast __attribute__((packed)) overrides
+STRUCTURE_SIZE_BOUNDARY.
+
+This matters when odd sized packed structs are nested inside each other.
+
+Given the purpose of #pragma pack is for compatibility with Win32, I think
+#pragma pack(1) act the same as __attribute__((packed)).
+
+The patch below fixes this.
+Tested with cross to arm-none-eabi.
+Ok?

+The gcc-3.x toolchains would contain all the targets by default. With gcc-4,
