eb4cd26383 from the comments at the top of the file: 
INSTALL -- somewhat generic kernel with a snowball's chance of
	   fitting on an install floppy.

This kernel MUST consist (for users' sanity) of a subset of
the GENERIC configuration.  It also should support X reasonably
(though the SysV SHM extensions won't work).

To avoid a maintenance nightmare, this kernel consists of GENERIC
with missing options/devices/etc. REMOVED rather than commented
out.  That makes it easy to diff agains GENERIC, to make sure that
it really is a subset of the functionality.

aeb93da3d7 Split FFS,QUOTA line, comment each individually. 
Add 'options INSECURE' so that the GENERIC kernel is happy with

9540190d45 This file, which will be included by <sys/cdefs.h>, will contain macros 
such as __warn_references() and __weak_reference() which are actually
machine dependant.  This will make it easier for ports that are being
bootstraped with ELF and ECOFF based toolchains.

This change also introduces a new macro, _C_LABEL(x).  _C_LABEL expands
its argument, an identifier, to a character string of the identifier
name as it is represented in an object file.

For most ports, _C_LABEL(x) will expand to "_x", for ELF based ports
_C_LABEL(x) will expand to "x".
