 * SUNSOFT
 * 	Solaris includes prototypes of bcopy/bzero/bcmp in strings.h
 * 	If strings.h is included after the macros below are defined, it
 * 	will break, therefore we force it to be included first since it
 * 	won't allow itself to be included multiple times. (Bug 1247568)
 *
 *	You can get back to the original X Consortium code by defining
 *	the macro __ORIGINAL_XORG_CODE
 *	Note that if __ORIGINAL_XORG_CODE is defined the resulting text
 *	is incompatible with strings.h so programs that attempt to include
 *	both this file and strings.h will fail to compile.
