+ * Simple if statement processor

+ * This module can be used to evaluate string representations of C language
+ * if constructs.  It accepts the following grammar:
+ *
+ *     EXPRESSION   :=  VALUE
+ *           |  VALUE  BINOP    EXPRESSION
+ *
+ *     VALUE        :=  '('  EXPRESSION  ')'
+ *           |  '!'  VALUE
+ *           |  '-'  VALUE
+ *           |  'defined'  '('  variable  ')'
+ *           |  variable
+ *           |  number
+ *
+ *     BINOP        :=  '*' |  '/'  |  '%'
+ *           |  '+' |  '-'
+ *           |  '<<'    |  '>>'
+ *           |  '<' |  '>'  |  '<='  |  '>='
+ *           |  '=='    |  '!='
+ *           |  '&' |  '|'
+ *           |  '&&'    |  '||'
+ *
+ * The normal C order of precedence is supported.

+ *     ParseIfExpression        parse a string for #if
