History
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 directory contains machine-specific files for the GNU C compiler.
It has a subdirectory for each basic CPU type.
The only files in this directory itself
are some .h files that pertain to particular operating systems
and are used for more than one CPU type.
