winedbg-eclipse - winedbg wrapper for Eclipse IDE

[Ilya Basin]

- Get Eclipse 3.7.2 CDT
- Import existing code as Makefile (a wine component or a standalone
- winelib program)
- Check "Automate discovery" in project properties/C/C++ Build/Discovery
- Create a standart C/C++ Application debug configuration
- Set *.exe.so as application
- Set winedbg-eclipse as GDB debugger
- fix bugs faster!
