System: NetBSD pattern 1.1_ALPHA NetBSD 1.1_ALPHA (PATTERN) #194: Thu Oct 19 00:34:35 EDT 1995 jtk@pattern:/u1/NetBSD-current/src/sys/arch/i386/compile/PATTERN i386


>Description:
	The NetBSD symbol defined in <sys/param.h> should be
monotonically increasing over time, so that code that needs to detect
the version of NetBSD can do so with things like '#if NetBSD > xxxx'.

The recent change to param.h reduced the integer value of this symbol.

If you want a more consistent symbol, have it include Year, month and
day (e.g. 19951117 for the slated Nov. 17th release).  That would be
larger than existing values and wouldn't pose a problem.

>How-To-Repeat:
Read the file, or try to compile code that auto-detects certain things.

>Fix:
