- * being compiled on:
- *
- * NetBSD 0.8 : NetBSD0_8 defined in <sys/param.h>
- * NetBSD 0.9 : NetBSD0_9 defined in <sys/param.h>
- * NetBSD 1.0 : NetBSD1_0 defined as 1 in <sys/param.h>
- * NetBSD 1.0A: NetBSD1_0 defined as 2 in <sys/param.h>
- *
- * The NetBSDx_y defines are mutual exclusive.
- *
- * This leads to something like this in pcvt_hdr.h (#elif is possible too):
