Does Gdb for win32 exist?

[Motohiko.Nagano@jp.sony.com]

Is there GDB which meet the following 3 requirements?

* Can "target exec" win32 native program (for example, notepad.exe)
* Can debug multi-thread program
* Can signal

I want to use GDB on Windows98 or Windows 2000.

Using gdb in cygwin1.1.2, I get the following error. 

(gdb) target exec E:\\WINNT\\notepad.exe
"E:\WINNT\notepad.exe": not in executable format: File format not recognized

Using gdb in cygwin B20.1,  I cannnot debug multi-thread program.

If someone knows the GDB which meet the requirements, please tell me it.


Thanks
