27 * Simple if statement processor
28 *
29 * This module can be used to evaluate string representations of C language
30 * if constructs.  It accepts the following grammar:
31 * 
32 *     EXPRESSION	:=	VALUE
33 * 			 |	VALUE  BINOP	EXPRESSION
34 *			 |	VALUE	'?'	EXPRESSION ':'	EXPRESSION
35 * 
36 *     VALUE		:=	'('  EXPRESSION  ')'
37 * 			 |	'!'  VALUE
38 * 			 |	'-'  VALUE
39 *			 |	'~'  VALUE
40 * 			 |	'defined'  '('  variable  ')'
41 * 			 |	variable
42 * 			 |	number
43 * 
44 *     BINOP		:=	'*'	|  '/'	|  '%'
45 * 			 |	'+'	|  '-'
46 * 			 |	'<<'	|  '>>'
47 * 			 |	'<'	|  '>'	|  '<='  |  '>='
48 * 			 |	'=='	|  '!='
49 * 			 |	'&'	|  '^'  |  '|'
50 * 			 |	'&&'	|  '||'
51 * 
52 * The normal C order of precedence is supported.
53 * 
54 * 
55 * External Entry Points:
56 * 
57 *     ParseIfExpression		parse a string for #if
