John Polstra 98bf848b69 Add a new predefined preprocessor symbol "__FreeBSD_cc_version",
with a numeric value that describes the feature level of the
compiler.  This can be used to check for the presence/absence of
FreeBSD-specific compiler features.  The value is a decimal number
whose digits have the form VRRRRFF, where:

	V    = Compiler vendor.  0 (elided) means gcc.
	RRRR = Vendor's version number, e.g., 2721 for the current
	       gcc version (2.7.2.1).
	FF   = FreeBSD-specific revision level.  00 means the stock
	       compiler from the vendor.

The value of "__FreeBSD_cc_version" is hard-coded in
"src/contrib/gcc/config/i386/freebsd.h" and must be incremented
when new FreeBSD-specific compiler features are added.  I considered
simply picking up the value of FreeBSD_version from <osreldate.h>.
But that would break cross compiles of gcc.

This is the top level of the FreeBSD source directory.  This file

For copyright information, please see the file COPYRIGHT in this
directory (additional copyright information also exists for some
sources in this tree - please see the specific source directories for
more information).

The Makefile in this directory supports a number of targets for
building components (or all) of the FreeBSD source tree, the most
commonly used one being ``world'', which rebuilds and installs
everything in the FreeBSD system from the source tree except the
kernel and the contents of /etc.  Please see the top of the Makefile
in this directory for more information on the standard build targets
and compile-time flags.

Building a kernel with config(8) is a somewhat more involved process,
documentation for which can be found at:
   http://www.freebsd.org/handbook/kernelconfig.html
And in the config(8) man page.

The sample kernel configuration files reside in the sys/i386/conf
sub-directory (assuming that you've installed the kernel sources), the
file named GENERIC being the one used to build your initial installation
kernel.  The file LINT contains entries for all possible devices, not
just those commonly used, and is meant more as a general reference
than an actual kernel configuration file (a kernel built from it
wouldn't even run).
