   * 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 ':'	EXPRESSION
   *
   *     VALUE		:=	'('  EXPRESSION  ')'
   * 			 |	'!'  VALUE
   * 			 |	'-'  VALUE
   *			 |	'~'  VALUE
   * 			 |	'defined'  '('  variable  ')'
   * 			 |	variable
   * 			 |	number
   *
   *     BINOP		:=	'*'	|  '/'	|  '%'
   * 			 |	'+'	|  '-'
   * 			 |	'<<'	|  '>>'
   * 			 |	'<'	|  '>'	|  '<='  |  '>='
   * 			 |	'=='	|  '!='
   * 			 |	'&'	|  '^'  |  '|'
   * 			 |	'&&'	|  '||'
   *
   * The normal C order of precedence is supported.
   *
   *
   * External Entry Points:
   *
   *     ParseIfExpression		parse a string for #if
