+ * Meaning of the names I chose (vaxlinux people feel free to correct them):
+ * swahw32     swap 16-bit half-words in a 32-bit word
+ * swahb32     swap 8-bit halves of each 16-bit half-word in a 32-bit word
+ *
+ * No 64-bit support yet. I don't know NUXI conventions for long longs.
+ * I guarantee it will be a mess when it's there, though :->
+ * It will be even worse if there are conflicting 64-bit conventions.
+ * Hopefully, no one ever used 64-bit objects on NUXI machines.
