/* cprefix.h:  This file is included by assembly source which needs
 *             to know what the c-label prefixes are. The newer versions
 *	       of cpp that come with gcc predefine such things to help
 *	       us out. The reason this stuff is needed is to make
 *	       solaris compiles of the kernel work.
