[Dev-C++] "Windows" vs. "Console"

I have been working through Stroustrup's "The C++ Programming Language" 
Special Edition.  I have run into a problemcompiling a program that 
Stroustrup says compiles and runs on his system, which I believe is a 
Unix system.

The code (p.109) that doesn't compile is the following:

#include <iostream>
#include <string>
#include <map>
#include <cctype>
using namespace std;

//    ENUM p.109
enum Token_value{
   NAME,        NUMBER,        END,
   PLUS='+',    MINUS='-=',    MUL='*=',    DIV='/',
   PRINT=';',    ASSIGN='=',    LP='(',        RP=')'

The error I get is the following:

    'LP' redeclared as different kind of symbol

This error comes from a statement in winnt.h, which is not included.

The problem is, I have been to the C++ Learning newsgroup, and after 
letting them see that winnt.h is not included, etc., etc., they have 
left me with "there must be a switch in your application/IDE 
configuration that is trying to write a Windows program.  You need to 
select configuration switches that produce a 'console' program in 
Windows or a DOS program."

I am using Bloodshed 4.9.8.7, and I have never had to change the config 
to compile and run other programs that come up in a DOS window.  And I 
have never changed the options in "Compiler Options".  And also, the 
options that indicate trying to support C constructs, I selected "No", 
since I am trying to un-confuse myself and learn C++ only.

Does anybody have any ideas why this error from winnt.h is appearing.
