+*               modified JCD 27 Apr-88 for AMIGA
+*      cext.h -- extensions to c to make it more portable
+* Copyright 1989 Carnegie Mellon University

+*******************************************************************
+
+cext must provide the following definitions:
+
+true     -- a  constant
+false     -- a boolean constant
+private -- defined as static, used to declare local functions
+public     -- defined as empty string, used to declare exported functions
+boolean -- a new type
+byte     -- unsigned 8-bit quantity
+ushort     -- unsigned 16-bit quantity
+ulong     -- unsigned 32-bit quantity
+Pointer -- pointer to char, a generic pointer
+ABS()     -- absolute value of any type of number
+MAX()     -- maximum of two numbers
+MIN()     -- minimum of two numbers
+ROUND()	  -- round a double to long		     
+
+NULL     -- pointer to nothing, a constant
+EOS      -- end of string, a constant '\0'
+MALLOC(x)     -- allocates x bytes
+FREE(x)     -- frees something from MALLOC
+AVAILMEM     -- tells how much memory is available.
+                   (N.B.: no parens, no args.)
+EXIT(n)  -- calls exit(n) after shutting down/deallocating resources
