+Subject: [PATCH] Fixup bswap.h macros
+
+The SWAP and SAME names used for the macros are named incorrectly, they should
+be called LITTLE_ENDIAN_TO_NATIVE resp. BIG_ENDIAN_TO_NATIVE. This also means
+that they will do the wrong thing on bigendian if used as intended in the
+previous version of bswap.h, but the WORDS_BIGENDIAN define which is checked
+for does not get defined by standard C headers, so we end up using the
+"/* Little endian */" block on big endian machines too, which makes things
+work with the old version there too. So this was a case were 2 wrongs make a
+right.
+
+This patch thus does not change anything functionally, but it does make the
+code read correctly.
