modification history
--------------------
01g,22sep92,rrr  added support for c++
01f,06aug92,ccc	 added function prototypes.
01e,26may92,rrr  the tree shuffle
01d,26may92,ajm  got rid of HOST_DEC def's (new compiler)
		  updated copyright
01c,04oct91,rrr  passed through the ansification filter
		  -fixed #else and #endif
