Does Gdb for win32 exist?

Does Gdb for win32 exist?

[Motohiko.Nagano]

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

Thank you very much! I tried it (p 'Foo::version') in gdb 5.0 and it works.
And now I have one more question: how I can examine a value of a variable
in anonymous namespace?

You have to know how it's really being named. nm <your
executable>|c++filt|grep -i <the variable name>
See, the real problem is that namespaces don't generate any debug info,
and aren't symbols, so they don't really exist, so to speak.
The reason quoting it works is because it also matches it against the
demangled names.
