Subject: config cannot handle OPTIONS with numeric characters.
Index:	etc/config/config.y 4.3BSD

Description:
	When using config(8) to build kernels for 4.3BSD, if one follows the
	instructions in "Installing and Operating 4.3BSD on the VAX" and
	try to enable TCP compatibility with 4.2BSD, config gives a syntax
	error and creates an incorrect Makefile.

Repeat-By:
	Go to /usr/src/sys/conf.  Make a configuration file, TEST, with a
	line that reads 
		OPTIONS	COMPAT_42
	Make a directory ../TEST
	Run
		/etc/config TEST
	Observe the syntax error message.  Examine the Makefile in ../TEST,
	noting the "-DCOMPAT_" incorrectly placed therein.
	
Fix:
	Apply the following patch to /usr/src/etc/config/config.y
	A similar patch can be applied to the 'Mkoption' production for
        completeness, but I have not done it.
