Strange error: Invalid option `-undef'

I am getting a strange error when I try to compile a small program that I made,
the source is as follows:

// codepagechecker.cpp
// [insert GPL]

#include <iostream.h>

void main(void)
  unsigned char Tegn1;

	cout << "Please enter the character you wish to use : ";
	cin >> Tegn1;
	cout << "\nYou entered: " << Tegn1 << ", which is decimal " << (int)Tegn1;
	cout <<  " and hexadecimal " << hex << (int)Tegn1 << ".";

Here's all the output bash and cpp provided me with:

BASH.EXE-2.02$ g++ codepagechecker.cpp -o codepagechecker.exe
cpp: Invalid option `-undef'

I never entered the option -undef anywhere, so I would be very gratefull
if somebody told me what I, or Cygwin, is doing wrong.

Thanks in advance.

May you live long and spamless,
